It looks like the ‘loop’ for your posts is missing.

In your source, you mention http://www.theacerguy.com/forum/bb-templates/theAcerGuyForum/forumStyle.css which doesn’t exist, and really should be in my-templates

It’s really like your topic.php is missing all the stuff from <?php do_action('under_title'); ?> down to the if open then reply_ok.

Do you have deep integration going on? You seem to be pulling WP header stuff down.
