We recently updated to Mediawiki 1.36. I'm testing some of our installed skins under it.
Use of Erudite is causing these warnings to be printed on the top of each page:
Deprecated: SkinMedik overrides setupSkinUserCss which was deprecated in MediaWiki 1.32. [Called from OutputPage::getRlClient in /var/www/html/w/includes/OutputPage.php at line 3017] in /var/www/html/w/includes/debug/MWDebug.php on line 376

I have no idea why we are running debug code on a production server. I guess that's a separate issue for the Mediawiki folks.
My apologies if this is not a Erudite issue.
