Hi everyone,

my web host recently transferred from a Cpanel to an H-Sphere cluster. After the transfer, I seem to encounter the following error:
If cookies are deleted, I can access my site ( http://www.geekylife.gr/blog/ ). However, once a session is created, either by trying to log in or navigating through the site, all that appears are blank pages.

You can see the phpinfo() here: http://www.geekylife.gr/phpinfo.php in case that helps (I was previously using PHP 5, before the transfer). The watchdog table doesn't have any info on this. In settings.php I have touched nothing but the database url.
