I've been trying to sort out what's up and why Social Profile is mis-behaving with my Mediawiki installation.
If you try to edit your profile you're given the error message "Fatal error: Call to undefined method MediaWiki\MediaWikiServices::getLinkRenderer() in /home/kitsufo/public_html/cosc2017/extensions/SocialProfile/UserProfile/UserProfileClass.php on line 232" If you try to upload an Avatar you get the error message "Fatal error: Call to undefined method MediaWiki\MediaWikiServices::getLinkRenderer() in /home/kitsufo/public_html/cosc2017/extensions/SocialProfile/UserProfile/UserProfileClass.php on line 232"
The problem seems to be connected as the error messages match, and the error points at the same file/line. Hopefully this can get resolved soon... The site it's on is Children of StarClan, in case you want to look into my exact configuration.
