If I click the "Enable/Disable PHP 5" link in control panel I see "PHP 5 is Installed! Remove PHP 5 from Your Account!", which I assume means PHP is enabled?
But if I look at my config in CP I see:
PHP version 4.4.8
And If I call the phpinfo(); function it also gives me PHP Version 4.4.8.. Is there something else I have to do to enable it??

On a related note.. Do most of the servers have the XSLT extension installed for PHP?
