CSS for integrating phpBB into WordPress

Hi all,

I’m trying to use the “phpBB inside WordPress” feature in the Theme Integration section, but after going through it (it appears successful), this is what I get on the page in question:

See how the forums are all squished into what looks like about 300px of space? Any idea why that is happening and how I can fix it?

Thanks, in advance!
