Ioncube loader error

I just moved my forum from one host to another. I did a complete copy of the file system for the vhost from one to the other. Now I am getting ioncube loader errors:

Site error: the file /var/www/vhosts/touch-buddy.com/httpdocs/forums/vbseo.php requires the ionCube PHP Loader ioncube_loader_lin_5.1.so to be installed by the site administrator.

I've tried changing ownership and perms to the files in the ioncube folder with no success.

I'm running CentOS 5.1 and Plesk.

Try downloading vBSEO unencrypted from the download area. Ioncube or Zend are no longer required to run vBSEO.

Thanks Juan. Would that do an in place upgrade of the existing version or would it require substantial configuration?

You can still use a backup copy of your existing vBSEO settings.

How do I backup the settings if I dont have access to the admin portal?

Ok I decided to purchase the upgrade service :P

Turns out it was SELinux blocking perms. That is fixed now, but I'm still going to upgrade to latest rev of Vbseo.
