I've recognized your question from this post.
If you're left and right divs aren't displayed correctly, there's probably a IE related issue. You can hit F12 in IE8 to open the IE developer toolbar and see how the div is floated in the container. That's a good starting point. Do you actualy float these divs relative or absolute?
Edit after comment:
See this link for a sample
fixed the issue with the side containers. It was a problem with the div tags.
