[horde] Question about NAG saving

[Patrick De Zordo]

Have I to make some special install steps for NAG?
I can't create a new Task, as apache is giving back this message:
"The requested URL /horde/nag/t/save was not found on this server"

Same if I try to complete a Task:
"The requested URL /horde/nag/t/complete was not found on this server."

Is this a code issue or am I making some errors in config?

If code issue I could create a bug in buglist.. ;-)
