Error after moving to new server

Hello,

I'm just in the process of moving to a new server.

I backed up the database and imported it to the new server -> OK
I downloaded all the stuff from FTP and uploaded -> OK

But for some reason, whenever I wan't to access the site (NOT via the proper URL, just preview url as my domain still resolves to the old server) this error comes up:

Fatal error: Undefined class name 'vbulletinhook' in /home/me/public_html/includes/init.php on line 295

I have no idea what this could be, I can't even access the adminpanel.

Thanks for your fast replies

sry for replying late, I fixed the problem after replacing all the files... something must have gone wrong while uploading

thanks
