I manually upgraded my wiki site from version 1.33 to version 1.34 and have been receiving the following message stuck at the top of my wiki. Depreciated : Use of $wgLocalInterwiki – use $wgLocalInterwikis instead was deprecated in MediaWiki 1.23. I am unable to find a solution to this issue and have searched the internet and Media Wiki. Below are the stats for my system. Product Version MediaWiki 1.34.0 PHP 7.2.24 (cgi-fcgi) MySQL 5.6.45 ICU Any assistance is appreciated.
