I have just installed OTRS 2.3.1 and due to the limitations of my hosting package I had to install under /home/www/domain.name/otrs instead of /opt/otrs. I think there is an issue with error reporting as when accessing otrs/bin/cgi-bin/index.pl in debug mode the error shown above is returned as the 500 error - nothing obvious is shown in either my access or error logs. If I switch off debug mode the page loads perfectly but if I login as root@localhost the same 500 error is generated. Any suggestions as to how to fix this? DB connectivity is fine The following have been set in otrs/Kernel/Config.pm: $Self->{Home} = '/home/www/domain.name/otrs'; $Self->{ScriptAlias} = 'otrs/bin/cgi-bin/'; $Self->{'LogModule'} = 'Kernel::System::Log::SysLog'; $Self->{'LogModule::LogFile'} = '/home/www/logs/otrs.log'; Graeme
