HTTP 500 after creation of service

[Grayzatt]

Hi all,
Thanks for this great forum

Im working on OTRS 4.0.6 with ITSM, everything was working like a charm untill i created an "service" well all the other functions are still present but i cant access the "service" page anymore :/ if i delete the service from Db than i can open the page up again butthe error returns as soon as the service is created.
Im running Mysql

otrs.log shows nothing :/
Apache log shows:

Code: Select all

[Tue Apr 21 13:50:53 2015] -e:     (in cleanup) Can't call method "Get" on an undefined value at /opt/otrs/Kernel/System/AuthSession/DB.pm line 583.
[Tue Apr 21 13:50:53.728190 2015] [:error] [pid 25245] Can't use an undefined value as a HASH reference at /opt/otrs/Kernel/System/Service.pm line 1701.\n 

Does anyone have any ideas or do you need something else?
i hope someone can point me in the right direction

500 errors are in /var/log/apache2 (or httpd)/error.log or equivalent.
