A few weeks ago I've successfully upgraded my phpbb2 to phbbb3.0
Last week my server has done some configuration changes to make some other script work. I didnt realize that time but I want just to mention it here since it is the only thing I find reasonable, but I dont know how... since they only allowed to work php4 and 5 at the same time...
Anyway... Now I see just blank page when I try to access the forum. So I decided to upgrade it to latest relase since this might overcome the problem but nothing changed...
All I see when I try to access the forum is blank page with no error message and with no content either

What is your recommendation to overcome this un-errorness problem?
