Domain: 3rdstrike.biz moved to 3rdstrikeperformance.com (at this time they are on different servers and both are active)

ZC Version: 1.3.8a

I used the following tutorial to transfer the site to the new server and update the config files: https://www.zen-cart.com/tutorials/index.php?article=99

The Admin area works great, but the index page (http://3rdstrikeperformance.com/index.php?main_page=) is blank.

This is what I am getting on my error log:

[29-Apr-2010 10:38:31] PHP Fatal error: Class 'phpBB' not found in /home/xrdstri/public_html/includes/autoload_func.php on line 79
Please let me know if you have any suggestions or need more information. I have searched both the forums and FAQ.
