I am posting this here, but it may apply to other Maian PHP scripts as well.

I simply commented out the line in timezones.php until I could figure out what was wrong. It turns out that 'Greenland' is no longer a valid PHP timezone. One must use 'America/Godthab' instead.

I made the change in the control/timezones.php file in both Maian Music and Maian Cart. Surely Sir Bennett will note this for future updates.
