bp-fun theme activity stream css issues

Hello. Can you please tell me how to correct this issue:

When you click on the Activity Stream page (when not set as home page) everything looks find. When the Activity Stream page is set to home, the content background shrinks and the content appears to bleed. I viewed this on several browsers and they're all the same.

I have attached a snapshot of this problem.

Thank you.

I wasn't able to attach the snapshot becasue of the size. I've since fixed the snapshot but now I can't attach it because there's not an option to upload.
