[kronolith] Problems with base.php

[Sebastian]

This is my second post, but no results.
After installing Horde(2.1), Imp(3.1) and nag I tryied to go forward with
kronolith. I created MySql database, activated it in horde's registry.php
and created a menu link. I also created /etc/mpasswd and entered the user
info to the config file. As soon as I try to access any of the kronoliths
files I get this:

Warning: Undefined index: calendar in
/var/www/html/horde/kronolith/lib/base.php on line 70
Warning: Undefined index: calendar in
/var/www/html/horde/kronolith/lib/base.php on line 70
Fatal error: Call to a member function on a non-object in
/var/www/html/horde/kronolith/lib/base.php on line 71

Help me!!!
What else is there to do?
