Thread:Project:Support desk/Mediawiki 1.20.4 Editing Page/reply

Hi!

From the error message I guess that you are using the extension CategorySuggest, right? This extension is not (yet) compatible with newer versions of MediaWiki, see the notes on Extension_talk:CategorySuggest.

The extension is maintained by Adam Franco. If I were you, I would [mailto:blog@adamfranco.com write him a mail], tell him about the error message and ask, if he can provide a fix.

It seems like this page contains helpful information on the error. If Adam removes the "&" infront of the second parameter of the function call, that should solve the issue.
