index.php line 565 is:
eval('print_output("' . fetch_template('FORUMHOME') . '");');
So, it sounds like you have a problem with your template.
I don't understand what all you have done at this point. Are you using a backup database? Was the backup make for the same version of vb that you just uploaded the files for? Did you upload all totally default files that you downloaded from vb.com?
Picking a forum at random, I went to
http://www.centexracingscene.com/for...isplay.php?f=5 and can see the page. However, there is no style to the page.
What do you have access to? Can you get into the admin cp?
