Ein schwerer Fehler ist aufgetreten:

I installed the php-date package on Debian to fix the Date_Calc class not found issue.

Horde is installed via Pear.

Do I have the right php package installed to provide the class Date_Calc?

Any ideas what the above error could be related to and how to fix it?

Best regards,
