Server Migration

[eluser]RaZoR LeGaCy[/eluser]
I just moved a website and the site only shows blank pages.

http://hellhorror.com
old server: MediaTemple
new server: ServInt
I did a plesk migration it is all blank.

I changed in config.php
$config['uri_protocol'] = "PATH_INFO"; === $config['uri_protocol'] = "AUTO";

Nothing works. How can I check mod_rewrite?

Need some ideas as to why it is showing blank pages.
