I recently let a freelancer do some work to our website and on first appearance it seemed ok. However, when I loaded the site in FF4 a couple of days later and then on older IE's, there is a really weird alignment issue with the whole contentMainWrapper bouncing over to the right. Something is pushing it across the screen to the right and I have analysed it in FireBug but cannot find the culprit.

Does anyone with FF4 have a few minutes to look at this? It's driving me mad and the freelancer is saying he hasn't changed anything that can have caused this. He's lying though, it was fine before.

There are three or four validation errors on our home page that weren't there before, either. Maybe these will shed some light on this?
