Thanks cofcloga.
To elaborate: Login and go to your cPanel.
At the top, SWITCH THEMES to cPanel x3 (if you don't already have that as your default)
Scroll down the page approximately EIGHT sections to the Software and Services area
Click the icon with the PHP logo marked Select PHP Version.
The current PHP version is indicated near the TOP of the formatted section
You can alter the VERSION by using the DROP DOWN MENU and then clicking the "Set as current" button next to the drop down.
This will SAVE the newly SELECTED version.
There is a SAVE button at the lower left corner, but it seems to be designated to specific modifications to different versions.
Of course, if you make no changes, hitting SAVE will not hurt, right?
I then logged out (upper right) and came back in to confirm the changes were in affect.
You can then return to the x10Hosting Basic theme through the SWITCH THEMES again.
