Hi all, I have the same problem as describe in the FAQ 4200371 After the installation of the ITSM 3.0.5 module on OTRS 3.0.10 under Ubuntu : (before the module install the OTRS works fine with all pages) "Login is not possible neither for agents nor for customers. Message "Your browser is too old. Please read the documentation...." will be displayed even on latest versions on different browsers. " But the solution in the FAQ don't work ! FAQ4200371 solution remove everything in $OTRS_HOME/var/tmp/Cache search ZZZAuto.pm for lines like $Self->{'Frontend::Module'}->{'AgentStats'} = { ... }; and comment them out remove ZZZAAuto.pm and run afterwards $OTRS_HOME/bin/otrs.RebuildConfig.pl run following command "$OTRS_HOME/bin/otrs.LoaderCache.pl -o delete Other idea ? Thanks Vincent
