Restore server image (ispconfig)

[syduck]

Hi I built a server from an image of an existing perfect server centos setup with ispconfig. (i am testing a backup restore of an existing server). I changed my hosts file to point to my new server. Everything works as it should but when i try to view one of the clients websites i get a blank screen, no errors or source code. I can view the ispconfig cpanel and squirrel mail no problem and access all the ftps and the files are still there. I changed the server ip from the ispconfig cpanel and changed the sites ip address in the ispconfig cpanel as well but still they dont load.

any insights?
