I'm trying to switch my website over to another server but eveything that uses the database is screwing up.

I made a dump and restored it onto my new server fine. I can look at it via phpMyAdmin and change it via phpMyAdmin. But when i use my scripts (a custom script for my site, and vbulletin) all I get is blank pages. No errors, just blankness. I can create and execute normal PHP scripts but anything that uses my one database isn't working.

I installed another copy of vbulletin on a different database on the same server and it works perfectly fine.

Any ideas?
