I just got an x10 hosting account and web page a few days ago, and even last night i was there and it was working fine. Now the page doesn't exist and i cant log-in to cPanel either.
Looks like it's up and working but redirects to a PHP script that is displaying a blank page. The most common reason is that it's trying to use a disabled PHP function.
Please upgrade your PHP version to intermediate: http://x10hosting.com/login <-- Use your FORUM user\pass. On the bottom left there is an option to upgrade.
