phpBB3, php5 and mysql

[Christoph Kukulies]

I'm in the process of moving a phpBB3 forum to a new machine (formerly 
5.2, now 7.1).
I also was so keen to move to php5 (was running php4 before, I believe).

I have the phpBB3 forum directory copied back into the DocumentRoot.
Mysql 4.1 is running, The database is there, I can log in to mysql and 
view the database.
I can get phpinfo.

Only I can't get the hell out of the phpBB3 forum. When I invoke the 
index.php
I get a blank page with an incomplete xml header. I have no idea were to 
look at the moment.

It looks a bit like php5 is not accessing the database (mysql) or 
something. Is there some module
or driver to be compiled in? I installed php5 now from ports with the 
apache mod_php5 module
being installed.

Any help welcome,
