Blank Page

[WalterE]

After upgrading Plesk to 9.3.0 Horde and AtMail is no more useable. On Horde i can see the Login screen, but after login i get a white screen. And on AtMail i only see white screen and no login. My System is Debian 5. I tried to Update the Plesk Panel to 9.5.1 because in the net someone says that will fix this error, but everytime i will get an error like this Error: Failed to check whether a new license key is available.

I hope someone can help me here.

Thanks
