I just tried updating MW on the server and got a pile of conflicts - did you change core files? Or copy a newer version via scp or something?
Oh - I thought you fixed the skin stuff - did you just send that to Markus then or so?
No, I just did these changes locally via CSS on MediaWiki:Vector.css, which overrides whatever the server has available for us. :) This is the reason why I was not able to do the tabs as sophisticated as they appear on Vectorata.
