Site help????

Hi there,

Can someone tell me why my content (sidebar+content) starts halfway through the header? I’m trying not to use margins to push them down due to IE reading them differently to other browsers.

Any help would be much appreciated, thanks in advance!

Also please don’t say anything about validation errors, I already know but I can’t fix them due to them being plugins and various other things.
