Page not using full width

[Luffer]

Hi,

I'm using the Simple:Press forum on my site and want it to display the full width. I'm using the "Full Width" page template but the main Forum page is not displaying correctly, it's like it's still stuck in the small width, but the sidebars have been removed.

The weird thing is, if you actually view a post then it works fine and does take up the full width. I'm assuming this is a theme problem, but I'll post the same question on the Simple:Press forum as well just in case. Any ideas?

You can see the problem here:
