Thumbnails not generating for external wikis
In the past several days, thumbnails are not being properly generated acrsso multiple wiki farms that use the wikimedia commons. Clicking through on the thumbnail returns a " Error Use thumbnail steps listed on https://w.wiki/GHai. Please contact noc@wikimedia.org for further information (a765913)"
Has something changed which has broken the standard functionality used by literally thousands of mediawiki wikis that rely on the wikimedia commons shard libraries? - 17:08, 7 March 2026 (UTC) Lestatdelc (talk) 17:08, 7 March 2026 (UTC)
- @Lestatdelc, as stated in mw:Common thumbnail sizes#FAQ, the error is probably due to the wikis not using one of the "standard" thumbnail sizes. Previously, the thumbnail will generate for any specified size via URL, but now MediaWiki requires one of the "standard" size to be specified when requesting via URL.
- However, this change was made in January 2026, so the problem might be something else if it only occurred in the past several days. Thanks. Tvpuppy (talk) 19:40, 7 March 2026 (UTC)
- If you are using mw:Extension:QuickInstantCommons, please update to the latest version. I just recently (like last week) fixed a bug in it to make it compatible with these changes. Bawolff (talk) 10:19, 9 March 2026 (UTC)
- And what if I don't want to use a "standard" thumbnail sizes? Then what? You used to be able to change the size of an SVG converted to PNG in the URL. Now you can't
- Can't you stop fucking up the site holy shit??!!! First you ban 90% of the users from editing images and now this, what are you going to break next? Yilku1 (talk) 19:49, 14 March 2026 (UTC)
- Please be civil and remember to be respectful to others. The change was implemented by MediaWiki and not by users here in Commons, but I certainly believe the change was made to improve the site rather than worsening it. Regarding your second point, I have no idea what you are referring to as I'm pretty sure "90% of the users" are not "banned from editing images". Thanks. Tvpuppy (talk) 20:04, 14 March 2026 (UTC)
- I'm fucking tired of EVERYTHING enshittifing, and now it's happening to wikipedia. Who asked for this?
- 90% of the users can't edit images. You have to ask like a pleb to the admins so you can edit, but only one for the image you asked. Another stupid change nobody asked. Yilku1 (talk) 20:15, 14 March 2026 (UTC)
- Explain me how breaking most thumbnails is improving the site? Yilku1 (talk) 03:08, 15 March 2026 (UTC)
- If you are using instant commons (not quickinstantcommons) there is a setting you can set where it downloads the original and then resizes locally (to any size you want). Bawolff (talk) 20:40, 14 March 2026 (UTC)

Updates for editors
- The Improved Syntax Highlighting beta feature, also known as CodeMirror 6, has been used for wikitext syntax highlighting since November 2024. It will be promoted out of beta by May 2026 in order to bring improvements and new features to all editors who use the standard syntax highlighter. If you have any questions or concerns about promoting the feature out of beta, please share.
- Some changes to local user groups are performed by stewards on Meta-Wiki and logged there only. Now, interwiki rights changes will be logged both on Meta-Wiki and the wiki of the target user to make it easier to access a full record of user's rights changes on a local wiki. Past log entries for such changes will be backfilled in the coming weeks.
- On wikis using Flagged Revisions, the number of pending changes shown on Special:PendingChanges previously counted pages which were no longer pending review, because they have been removed from the system without being reviewed, e.g. due to being deleted, moved to a different namespace, or due to wiki configuration changes. The count will be correct now. On some wikis the number shown will be much smaller than before. There should be no change to the list of pages itself.
- Wikifunctions composition language has been rewritten, resulting in a new version of the language. This change aims to increase service stability by reducing the orchestrator's memory consumption. This rewrite also enables substantial latency reduction, code simplification, and better abstractions, which will open the door to later feature additions. Read more about the changes.
- Users can now sort search results alphabetically by page title. The update gives an additional option to finding pages more easily and quickly. Previously, results could be sorted by Edit date, Creation date, or Relevance. To use the new option, open 'Advanced Search' on the search results page and select 'Alphabetically' under 'Sorting Order'.
View all 28 community-submitted tasks that were resolved last week. For example, the bug that prevented UploadWizard on Wikimedia Commons from importing files from Flickr has now been fixed.
Updates for technical contributors
- A new special page, Special:LintTemplateErrors, has been created to list transcluded pages that are flagged as containing lint errors to help users discover them easily. The list is sorted by the number of transclusions with errors. For example: Special:LintTemplateErrors/night-mode-unaware-background-color.
- Users of the Improved Syntax Highlighting beta feature have been using CodeMirror instead of CodeEditor for syntax highlighting when editing JavaScript, CSS, JSON, Vue and Lua content pages, for some time now. Along with promoting CodeMirror 6 out of beta, the plan is to replace CodeEditor as the standard editor for these content models by May 2026. Feedback or concerns are welcome.
- The CodeMirror JavaScript modules will soon be upgraded to CodeMirror 6. Leading up to the upgrade, loading the
ext.CodeMirrororext.CodeMirror.libmodules from gadgets and user scripts was deprecated in July 2025. The use of theext.CodeMirror.switchhook was also deprecated in March 2025. Contributors can now make their scripts or gadgets compatible with CodeMirror 6. See the migration guide for more information. - The MediaWiki Interfaces team is expanding coverage of REST API module definitions to include extension APIs. REST API modules are groups of related endpoints that can be independently managed and versioned. Modules now exist for GrowthExperiments and Wikifunctions APIs. As we migrate extension APIs to this structure, documentation will move out of the main MediaWiki OpenAPI spec and REST Sandbox view, and will instead be accessible via module-specific options in the dropdown on the REST Sandbox (i.e., Special:RestSandbox, available on all wiki projects).
- The Scribunto extension provides different pieces of information about the wiki where the module is being used via the mw.site library. Starting last week, the library also provides a way of accessing the wiki ID that can be used to facilitate cross-wiki module maintenance.

Opera browser data saver mode
this probably niche problem happened to me today. writing here in case anyone might have it too.
i couldnt edit using opera browser on my android phone. after some testing i realised that my ip is different (according to whatismyipaddress.com) when i use chrome and opera. turning off data saver finally makes ip the same and lets me be no longer affected by ip blocks.

Images seem to be broken
I'm into computer programming, and I've heard that wikimedia commons recently archived most of their images, but now none of them show up on my webpages. I don't know how to input images into my HTML code anymore.
here is a link that doesn't work.
pretty much all of the old images are broken like this, and they simply don't show up on my webpages. Dragonstudios36 (talk) 14:52, 20 March 2026 (UTC)
- Use https://upload.wikimedia.org/wikipedia/commons/thumb/9/92/Snowy_Mountain_Valley.jpg/1920px-Snowy_Mountain_Valley.jpg instead. Try using one of the sizes from this list: 20px, 40px, 60px, 120px, 250px, 330px, 500px, 960px, 1280px, 1920px, 3840px [Personally I find it really silly we are just breaking everything instead of just using redirects]. Near the top of the image page there should be a button labelled "use this file" which will give you html code to include the file. Bawolff (talk) 19:24, 20 March 2026 (UTC)
Tech News: 2026-13
Latest tech news from the Wikimedia technical community. Please tell other users about these changes. Not all changes will affect you. Translations are available.
Weekly highlight
- Wikimedia site users can now log in without a password using passkeys. This is a secure method supported by fingerprint, facial recognition, or PIN. With this change, all users who opt for passwordless login will find it easier, faster, and more secure to log in to their accounts using any device. The new passkey login option currently appears as an autofill suggestion in the username field. An additional "Log in with passkey" button will soon be available for users who have already registered a passkey. This update will improve security and user experience. The screen recording demonstrates the passwordless login process step by step.
- All wikis will be read-only for a few minutes on Wednesday, 25 March 2026 at 15:00 UTC. This is for the datacenter server switchover backup tests, which happen twice a year. During the switchover, all Wikimedia website traffic is shifted from one primary data center to the backup data center to test availability and prevent service disruption even in emergencies.
Updates for editors
- Wikimedia site users can now export their notifications older than 5 years using a new Toolforge tool. This will ensure that users retain their important notifications and avoid them being lost based on the planned change to delete notifications older than 5 years, as previously announced.
- Wikipedia editors in Indonesian, Thai, Turkish, and Simple English now have access to Special:PersonalDashboard. This is an early version of an experience that introduces newer editors to patrolling workflows, making it easier for them to move from making edits to participating in more advanced moderation work on their project.
- The Special:Block now has two minor interface changes. Administrators can now easily perform indefinite blocks through a dedicated radio button in the expiry section. Also, choosing an indefinite expiry provides a different set of common reasons to select from, which can be changed at: MediaWiki:Ipbreason-indef-dropdown.
- Mobile editors at several wikis can now see an improved logged-out edit warning, thanks to the recent updates from the Growth team. These changes released last week are part of ongoing efforts and tests to enhance account creation experience on mobile and then increase participation.
View all 36 community-submitted tasks that were resolved last week. For example, the bug that prevented mobile web users from seeing the block information when affected by multiple blocks has been fixed. They can now see messages of all the blocks currently affecting them when they access Wikipedia.
Updates for technical contributors
- Images built using Toolforge will soon get the upgraded buildpacks version, bringing support for newer language versions and other upstream improvements and fixes. If you use Toolforge Build Service, review the recent cloud-announce email and update your build configuration as necessary to ensure your tools are compatible.
- The API Portal documentation wiki will shut down in June 2026. API keys created on the API Portal will continue to work normally. api.wikimedia.org endpoints will be deprecated gradually starting in July 2026. Documentation on the API Portal is moving to mediawiki.org. Learn more on the project page.

- Can someone give a better explanation of the thing about notifications? I don't understand whether this is specific to notifications still on the user talk page or, if not, how it would affect already-archived talk pages. - Jmabel ! talk 20:07, 23 March 2026 (UTC)
- Don't know what you mean. Notifications are the thing that display in the dropdown in the top right. Info on the technical system it uses, Echo, can be found at mw:Extension:Echo. Apparently they want to delete notifications older than 5 years. Prototyperspective (talk) 22:44, 23 March 2026 (UTC)
- Ah, so this is presumably about notifications one has long since dealt with. Got it. I knew those were called notifications, but presumed it had to be something else, because who on earth looks at a notification more than a few days, maybe a month, after the fact? Five years?? (I guess someone cares...). - Jmabel ! talk 00:44, 24 March 2026 (UTC)

Annotations invisible for logged out users
Per title - COM:Image annotations are not displayed unless you are logged in. Qbli2mHd (talk) 01:11, 25 March 2026 (UTC)
- Well that makes sense because only logged in users can use gadgets. Nemoralis (talk) 18:39, 25 March 2026 (UTC)
- Hmm, it is actually loaded for all users via Common.js. It works for me in a private window (logged out). Nemoralis (talk) 18:47, 25 March 2026 (UTC)
- I think I understand where this comes from - annotations won't work if page width (determined on load) leads to image being resized. This happens when the window is too narrow to fit an image; annotations will work if you reload the page with a wider window; they won't work again if you make the window even wider, because a sidebar is inserted to the right and image is resized; they will work again if you make window wide enough to fit both the image and the sidebar.

Latest tech news from the Wikimedia technical community. Please tell other users about these changes. Not all changes will affect you. Translations are available.
Weekly highlight
- The Beta version of Abstract Wikipedia a new Wikimedia project which is language-independent, was launched last week. The project allows communities to build Wikipedia articles in their native language, which can be readily accessed by other users in their own languages. The wiki is powered by instructions from Wikifunctions and also based on structured content from Wikidata. Read more.
Updates for editors
- The Growth team is running an A/B test to evaluate a clearer, more user-friendly message that promotes account creation on wikis. Currently when logged-out mobile users begin editing, they see a jarring warning message that can feel abrupt and discouraging. This also presents temporary account editing as the default rather than encouraging account creation. The test is running on ten Wikipedias, including Arabic, French, Spanish and German. Read more.
- The Wikimedia Apps team is inviting feedback on how editing should work on the Wikipedia mobile apps. The discussion focuses on improving how users access editing tools when they tap "Edit". This is part of a broader effort to convert readers who develop an interest in editing, to access a more user-friendly pathway to start contributing.
View all 45 community-submitted tasks that were resolved last week. For example, an issue where citation fetching from the large newspaper archive Newspapers.com was no longer working, due to a block in Citoid requests, has now been fixed.

Did anyone else see this?
I went to Category:Tavares, Florida and on the {{Wikidata Infobox}} instance there I saw that the "official website" link read "Official Website of [somebody's name that started with I, think the second name started with H]". The link was correct and refreshing the page made it return to just "official website". Did anyone else see this or am I just losing my mind (small loss)? - The Bushranger (talk) 19:34, 1 April 2026 (UTC)
Bug with Notices
Noticed (heh) this evening that the 'Notices' tab on Commons is not allowing you to clear notices from other Wikimedia projects unless you clear it from that project. - The Bushranger (talk) 01:36, 2 April 2026 (UTC)
- Ah that's great news since I recently accidentally clicked on one of these multi-notification items from another project (one from Commons while on English Wikipedia). Looks like I didn't lose my notifications then. I think this bug is good to have as a safeguard but it would be much better if there was a setting to require confirmation if one marks multiple or even all notifications as read (and then the issue you described was fixed). See wish W472: Confirmation dialog to prevent accidental clicks on Mark All As Read for notifications in the ongoing Community Wishlist. Prototyperspective (talk) 13:37, 2 April 2026 (UTC)
Database servers in cluster31 are overloaded
I noticed today that when I try to access my watchlist page here in Commons from Edge (but the same problem also appears in Chrome - I see cluster26 mentioned there) an error message appears.
Sorry! This site is experiencing technical difficulties.
Try waiting a few minutes and refreshing.
(Cannot access the database: Cannot access the database: Database servers in cluster31 are overloaded. In order to protect application servers, the circuit breaking to databases of this section have been activated. Please try again a few seconds.)

Action Required: Update templates/modules for electoral maps (Migrating from P1846 to P14226)
Hello everyone,
This is a notice regarding an ongoing data migration on Wikidata that may affect your election-related templates and Lua modules (such as Module:Itemgroup/list).
The Change:
Currently, many templates pull electoral maps from Wikidata using the property distribution map (P1846), combined with the qualifier depicts (P180): electoral result (Q19571328).
We are migrating this data (across roughly 4,000 items) to a newly created, dedicated property: apportionment diagram (P14226).
What You Need To Do:
To ensure your templates and infoboxes do not break or lose their maps, please update your local code to fetch data from P14226 instead of the old P1846 + P180 structure. A list of pages was generated using Wikimedia Global Search.
Deadline:
We are temporarily retaining the old data on P1846 to allow for a smooth transition. However, to complete the data cleanup on Wikidata, the old P1846 statements will be removed after May 1, 2026. Please update your modules and templates before this date to prevent any disruption to your wiki's election articles.
Let us know if you have any questions or need assistance with the query logic. Thank you for your help! ZI Jony using MediaWiki message delivery (talk) 17:09, 3 April 2026 (UTC)

Tech News: 2026-15
Latest tech news from the Wikimedia technical community. Please tell other users about these changes. Not all changes will affect you. Translations are available.
Updates for editors
- The CampaignEvents extension now includes a new group goal-setting feature, enabling organizers to set and track event goals such as the number of articles created and participating contributors in real time. Similarly, participants can work toward shared targets and see their collective impact as the event unfolds. The feature is now available on all Wikimedia wikis. Learn more in the documentation.
The new watchlist labels feature (announced in Tech News 2026-07) is now available via VisualEditor, the source editor, and the 'watchstar' (or watch link, for skins that don't have a star icon). Previously it was only possible to assign labels via EditWatchlist. In all three places it is a new field following the expiry field.
View all 23 community-submitted tasks that were resolved last week. For example, the issue where talk pages on mobile with Parsoid are unusable after empty section headers, has now been fixed.
Updates for technical contributors
- The sub-referencing feature, which lets editors add details to an existing reference without duplicating it, will be gradually rolled out to more wikis later this year. Wikis using the Reference Tooltips gadget are encouraged to update their version (typically at MediaWiki:Gadget-ReferenceTooltips.js as shown here) to ensure compatibility. Other reference-related gadgets may also be affected.
- All Wikinews editions will be closed and switched to read-only mode on 4 May 2026. Content will remain accessible, but no new edits or articles can be added. This closure was approved by the Board of Trustees of the Wikimedia Foundation following extended discussions. Read more.
- The Action API has had several formats for requested output. One of them,
format=php, is being removed soon. Please ensure your scripts or bots use the JSON format. This removal should affect very few scripts and bots. - The Special:NamespaceInfo page now includes namespace aliases. For example "WP" for the "Project" ("Wikipedia") namespace on the German Wikipedia.

[Bug] Commons:Meet our photographers
Good evening everyone.
When viewing this page from a smartphone: , not all photographers appear. ComputerHotline (talk) 11:36, 7 April 2026 (UTC)
Persistent 0x0 image size error for PDF files
Dear all technical users, Commons (as well as all other projects using files from Commons) has experienced a persistent 0x0 image size error for PDF files. In short, the system fails to generate thumbnails of pages for certain PDF files (typically larger ones). This has seriously affected works on Wikisource, where "Failed to initialize OpenSeadragon, no image found." is displayed on affected pages. OCR is also disabled.
While Yann reported that purging and uploading dummy files (then reverting to the old file) sometimes work, it is not effective for other cases. He also mentions that the problem worsens in the few days. While a Phabricator report is created, it has stalled for many weeks.
Comments from experienced users are appreciated, and follow-up measures on Phabricator are even more appreciated, thank you.廣九直通車 (talk) 11:45, 8 April 2026 (UTC)
Image size issue
I just noticed that, apparently, on images, the links for "880 x 522 pixels" and "640 x 441 pixels" versions of images actually both link to the same size image ("960px-[imagename stuff]"). This can't be intentional, can it? The Bushranger (talk) 16:04, 9 April 2026 (UTC)
- @The Bushranger: since not all files are going to have the same aspect ratios, can you link to a file that is an example of what you are talking about? - Jmabel ! talk 20:16, 9 April 2026 (UTC)
- I do see something like this at File:En route from Mila 23 to Letea - 27 - water lilies.jpg: 640 × 427 pixels leads to "960...", 1,024 × 683 pixels and 1,280 × 853 pixels both lead to "1280...", "2,560 × 1,707" leads to "3840...". - Jmabel ! talk 20:21, 9 April 2026 (UTC)
- @Jmabel: , heres two: File:Vickers Valiant B.2 4Sep53.png ("680 x 360" and "800 x 450" both lead to "960...") and File:Vulcan at Manston - Flickr - Elsie esq..jpg ("640 x 441" and "800 x 552" both link to "960..."). - The Bushranger (talk) 20:26, 9 April 2026 (UTC)
- @Jmabel@The Bushranger The software only renders a fixed set of common sizes to reduce server loads - see mw:Common thumbnail sizes. Any usage of images loads one of these sizes and scales it in-page to the desired size. That's a change from a few months ago IIRC. It is somewhat frustrating that most of the default sizes listed on file pages don't match those sizes, so (as you experienced) the links are rather misleading.

- In short, the left hand does not know what the right hand is doing.
- Do we have any control over what sizes are offered on file pages, or do we have to wait for one set of WMF engineers to finally notice what another set of WMF engineers are doing? (If the latter, a phabricator report might speed this up.) - Jmabel ! talk 22:06, 9 April 2026 (UTC)
- This is a known issue, but it's one of those where we were mostly waiting for the dust to settle on the other changes wrt to file sizing before dealing with it. —TheDJ (talk • contribs) 07:39, 10 April 2026 (UTC)
- @Pi.1415926535 so someone changed how thumbs are created a few months ago and now we see a lot of problems because of that? I wonder if #Persistent 0x0 image size error for PDF files is one of the results. This problem pretty much closes down the use of pdf on Wikisource. --MGA73 (talk) 09:01, 12 April 2026 (UTC)

Tech News: 2026-16
Latest tech news from the Wikimedia technical community. Please tell other users about these changes. Not all changes will affect you. Translations are available.
Weekly highlight
- Experienced editors are invited to test the Article guidance feature, designed to help less-experienced editors create well-structured, policy-compliant Wikipedia articles. Testing instructions are available. Also, after reviewing the outlines, please provide feedback on the project talk page. Based on your input, the feature will be refined and transferred to the pilot Wikipedias to translate and adapt. Check out the video explaining the feature.
Updates for editors
- On most wikis, all autoconfirmed users can now use Special:ChangeContentModel page to create new pages with custom content models, such as mass message lists, making custom page formats more accessible. Check Special:ListGroupRights for the status of your wiki.
- The Growth team has launched an account creation experiment to evaluate whether adding an account creation button to the mobile web header increases new account registrations and encourages more mobile users to contribute to the wikis. The experiment is currently live on Hindi, Indonesian, Bengali, Thai, and Hebrew Wikipedia, and targets 10% of logged-out mobile web users.
View all 30 community-submitted tasks that were resolved last week. For example, an issue where VisualEditor could get stuck loading on Windows devices with animations turned off, has now been fixed.
Updates for technical contributors
- Starting later this week, Abuse filter editors who have the Improved Syntax Highlighting beta feature enabled will have CodeMirror instead of CodeEditor as the editor at Special:AbuseFilter. This is part of the broader effort to make the user experience more consistent across all editors.
- Tools and bots that access the Notifications API (
action=query&meta=notifications) will need to update their OAuth or BotPassword grants to also include access to private notifications. - Due to a library upgrade, listings on category pages may be displayed out of order starting on Monday, 20th April. A migration script will be run to correct this, and will take hours to days depending on the size of the wiki (up to a week for English Wikipedia).
Detailed code updates later this week: MediaWiki
