Thread:Project:Support desk/Fatal error: Call to a member function addWikiMsg() on a non-object in /home/username/public html/wiki/includes/specials/SpecialLinkSearch.php on line 82/reply (24)

I have this same error on my wiki when I click on the Special page for the link search (the search page doesnt load and it gives an error). Its 1.18.0 (correctly updated from previous MW, deleted old files, everything else works). "Fatal error: Call to a member function addWikiMsg on a non-object in /home/[user] ... /includes/specials/SpecialLinkSearch.php on line 82". I can turn on debugging and stuff to get some more detail messages and post them here. Whats the best way to do that?
