[horde] Error After Installation of Nag

[Helmut Schiefer]

Dear List,

a few minutes ago I installed NAG on my server. Installation runs god  
and without without any problems.

I copied the database from my existing server to the new hord 5 system  
and I got the following problem.

If I click on Nag in the Top Level Navigation I got a blank page back  
and the follwing in the Log:

If i use Task > Search from the Top Level Menu, I got a left side  
Navigation and a search screen. If I search, I got a blank page back.

Any Idea?
