Hello all, I'm new to this whole Geeklog and pretty much the PHP thing and was working on getting a site and phpbb2 all setup. I uploaded all the files and configured them all to what I believe is correct and put them all on the ftp where and how I was supposed to according to the readme. And after install/configure of PHPBB2 through the yourdomain/install/install.php and then going into the Plugins part of Geeklog after going into my admin and trying to install phpbb2 as a plug-in I get this error.

Hacking attempt
Warning: Cannot modify header information - headers already sent by (output started at http://kappatappakegga.com/glphpBB2/common.php:1) in /home/kappatap/public_html/lib-common.php on line 811

Fatal error: Call to a member function on a non-object in /home/kappatap/public_html/admin/plugins/phpbbbridge/install.php on line 140

If anyone knows what this error is and how to fix it if you could post back would be greatly appreciated. Thank you in advance.
