No updates, but site changed

[hcksharp]

Hi folks,

I have encountered a strange issue with FF displaying my website with a shift in the nav menu, as well looks like some things get re sized. This issue happened pretty much over night, without me doing any updates or work on the site.

Site looks fine in IE7.

Been racking my brain on what happened, but no ideas so far.

Would appreciate feedback on potential causes. Site is at

Thanks in advance,

Thomas

erm... I get a blank page(with a scroll bar)...

Can I make a tip, if your going to go using XML short tags, could you serve the page as XML?
