I enabled debugging and get the following error: [Wed Feb 5 19:07:29 2003][Error][Kernel::System::AuthSession::IPC::WriteSHM][79] Can't write session data. Max. size (180224 Bytes) of SessionData reached! Drop old sessions! [Wed Feb 5 19:07:29 2003][Debug][ModPerl::ROOT::ModPerl::Registry::opt_otrs_bin_cgi_2dbin_index_ 2epl::handler][603] Global handle stopped. Now I know it sounds easy, but I chmoded the complete /opt/otrs to 777 Another interesting fact: When I call the installer.pl I get Kernel/Config.pm isn't writable. But the directory as well as the Config.pm are owned by nobody and chmodded to 777 Last thing: Look at the weird group the logfile is owned by: -rw-rw-r-- 1 nobody 4294967295 40011 Feb 5 19:36 /tmp/otrs.log Can anybody see something from this? Again, the simple CGI version works totally fine. Thanks
