ITSM,strange errmsg when clicking Service button in nav bar

[heinrich_neumann]

When clicking the "Service" button in the navigation bar I get ->
Software error:
Can't use an undefined value as a HASH reference at /usr/share/otrs//Kernel/System/Service.pm line 450
Syslog only shows ->
Tue May 24 14:49:39 2011 error OTRS-CGI-10 Class not found in database!
ITSM Installation was quite annoying, especially Change Mgmt; had to run RebuildConfig.pl couple times,restart apache or reboot whole server.
But finally all packages show status "Installed".
OTRS 2.4.7, ITSM 2.0.3, Ubuntu 10.04.
Vielen Dank in advance!

this sounds like CI class not configured
reinstall general catalog?

Danke Wolfgang,
there is no REINSTALL option, so you have to probably uninstall first; and UNINSTALL ends up in "can't be
uninstalled because of dependencies". Will now do a complete new installation; not a big deal since running my
test env in virtual machine.

Bitte, gerne!
That's of course the best option
