Description

Steps to replicate the issue (include links if applicable):

  • Open any page on docker image mediawiki-docker 1.44.0

What happens?:
Deprecated: Use of MediaWiki\Skin\Skin::appendSpecialPagesLinkIfAbsent was deprecated in MediaWiki 1.44. [Called from MediaWiki\Skin\Skin::buildSidebar in /var/www/html/includes/skins/Skin.php at line 1639] in /var/www/html/includes/debug/MWDebug.php on line 386
...in the page header.

What should have happened instead?:
No header error.

Software version (on Special:Version page; skip for WMF-hosted wikis like Wikipedia):
Product Version
MediaWiki 1.44.0
PHP 8.1.33 (apache2handler)
ICU 72.1
MariaDB 11.8.2-MariaDB-ubu2404

Other information (browser name/version, screenshots, etc.):
The number of hits on Google to wikis with this error now popping up would indicate this is a genuine issue, e.g.:

(Sidenote: production wikis shouldn't display deprecation warnings to the user, that means the site is misconfigured)

@Pppery - noted, thank you. I'm administrator user, assume that is why. This is a standard docker container install, settings for this have not been changed from default, so assuming sane defaults this should not be showing for users given your comment...

(The sidenote was about google search, not your Docker wiki)

Note that in this case the deprecation warning indeed has to be triggered by a leftover configuration that needs to be tweaked. See the task this was marked a duplicate of.
