Can you please check the following? (copied from https://www.mediawiki.org/wiki/Help:Locating_broken_scripts)
Be sure you have an up-to-date configuration
- First, ensure your browser is up to date. MediaWiki features and some scripts are not supported by old browsers for safety reasons.
- Then, purge the cache for the page to force the page to be redisplayed from its source or scripts to restart.
Those two points solve most issues.
If you have a tool like "NoScript" or ad blockers installed on your web browser, then make certain that scripts are enabled for wikipedia.org, wikimedia.org, mediawiki.org, and wikidata.org.
Test if you have problems related to user scripts or gadgets
To test if your problem is linked to user scripts or gadgets, you can try to temporarily deactivate all on-wiki scripts at once.
To do so, add ?safemode=1
to the web address (URL) of the page on which you see the problem. Example: https://www.mediawiki.org/wiki/Special:Watchlist?safemode=1
If the URL already includes a ?
, append &safemode=1
instead. Example: https://www.mediawiki.org/w/index.php?title=Special:Watchlist&safemode=1
If you still have problems on the page you are testing with the safe mode, and your browser is up to date, please report here.
If you don't have the problem anymore using the safe mode, it means you have an issue with a user script or gadget. You have then to identify the problem.
