Having some browser issues

[ghealy44]

I recently started messing with vbulletin, its been relatively easy to modify up to this point. My issue is that In firefox and Internet explorer my site looks perfect. In chrome and safari, the vbulletin menu is off and behind my custom navigation.

the site is here: www.twitchthesticks.com/forums

a main issue is that I cant fudge around in firebug since its safari that is jacked, but im hopeful that maybe someone can check me out and tell me where I screwed up. that menu specifically is lower in the header code, i havent touched anything down there. seems like it was fine one minute, gone the next.

thanks in advance to whoever can help me out.
