I installed the phppbb seo ultimate mod. Everthing seemed to work. Now wheni go to my forum it shows up but when i click on a category a blank page shows up. I can still go to my ACP. Im not sure what the problem is.

Any questions or comments would be greatly appreciated.

So i will try to be more specific. When i click on a link on my forum i go to something like this

-http://www.studentpavement.com/phpBB3/climate-change-f5.html

First off i put the contents of phpBB3 in my site root so i think it might be something with the phpBB3 part of the url. But even if i take the phpBB3 out it still just takes me to a blank page.

Im haven't done anything with my .htaccess file and that might be the problem. I don't really know where it is or what to do with it.

Please help me im really lost.
