Please don't create multiple threads for the same issue. Your original thread is still on the first page.
The script you are using is encoded for the Zend Optimizer runtime, which is not currently installed on the server. (In other words, it's not a plain PHP script or HTML page.) I am not in a position to know whether x10Hosting has any plans to install the runtime; I do know that it means automated scanning for violations of the Terms of Service and Acceptable Use Policy becomes more difficult if compressed scripts are allowed, so it may not simply be an oversight.
