[otrs] Update of RHEL 4 broke my OTRS v.2.0.4 installation.

Hi. After I patched my RHEL 4 system with all the latest updates and rebooted the system, I started recieving this following message: Software error: Permission denied at /opt/otrs/bin/cgi-bin/../../Kernel/System/Log.pm line 79, <PRODUCT> line 4. For help, please send mail to the webmaster (), giving this error message and the time and date of the error. I cannot figure out what the problem is. Does it have to do something with writing information to a log file or? Please help :) Thank you, /Stefan Hogdahl
