Layout issues with Internet Explorer 7

My b2evolution Version: Not Entered

Here is what the site looks like in IE7. You can see the right menu is being covered by the center content layer.

Here is what it is supposed to look like (Firefox).

Do you think this is a CSS or validation issue, or is it more to do with a B2Evo incompatibility with IE7?

It's probably a [url=http://validator.w3.org/check?uri=http://www.carnifexpress.net/blogs/]validation[/url] problem, tad hard to tell much else until you clear all the errors.

Form is loading...
