My php script returns a blank page. By searching the forum, I determined that it was because of a PHP fatal error; and that php error reporting is turned off. To turn php error reporting on, the post went on to say that you had to be using cPanel x3. When I click on the Switch cPanel mode link at the top of the page, I get the Keep x10Hosting Basic or Switch to cPanel x3 dialog box. Clicking the Switch to cPanel x3 button, I'm asked to log in again. But I'm returned to the x10 hosting Basic control panel.
