Session Glitch With Server Switch

[matimer]

I've got an old modded 4images 1.7.1 and just moved to a php5 server and everything works except the admin page is white and I can't get the sessions to acknowledge I'm logged in.  The only mod I'm using is the php2 bridge http://www.4homepages.de/forum/index.php?topic=4315

So it affects the session.php file directly.
