Thread:Project talk:Support desk/gallery tab not working in new Mediawiki 1.8 upgrade/reply (6)

I suggest you replace the "skins/common/shared.css" file on your MediaWiki server with this file:

http://svn.wikimedia.org/svnroot/mediawiki/tags/REL1_18_1/phase3/skins/common/shared.css

That should fix it.
