Nice! I was having the problem and I host with Media Temple… Turning the SAfe Mode off worked perfectly!
On DV Server using Plesk:
(dv) 3.x Customers can disable PHP safe mode local value for a domain from within Plesk.
Login to Plesk
Click on Domains
Click on the domain
Click on Setup under the Hosting section
Under the services section make sure PHP support is checked, but safemode should be unchecked.
Click Save.
