bbPress.org

You changed the installation from forums to bbpress, but you didn’t make the change in the config.php. So, your forum is at http://www.reviewsaurus.com/bbpress/, but the config has $bb->uri = 'http://www.reviewsaurus.com/forums/'; You need to change one or the other (either the folder name or the URI in the config) for it to work.

As proof, I can see http://www.reviewsaurus.com/bbpress/bb-templates/kakumei/style.css just fine.
