Hello all, I'm very interested in using ACL CloseParentAfterClosedChilds, but when I enable the ACL by putting the following lines in my Config.pm file: $Self->{'Ticket::Acl::Module'}->{'1-Ticket::Acl::Module'} = { 'State' => [ 'closed succesful', 'closed unsuccesful', ], 'Module' => 'Kernel::System::Ticket::Acl::CloseParentAfterClosedChilds' }; I always get back this error: Can't locate object method "LinkList" via package "Kernel::System::LinkObject" at /opt/otrs//Kernel/System/Ticket/Acl/CloseParentAfterClosedChilds.pm line 67. I'm running OTRS 2.2.7 and i use latest version (1.9) of CloseParentAfterClosedChilds.pm Any idea? Why a double slash after /opt/otrs in the error? It is normal? I have: $Self->{Home} = '/opt/otrs' In my Config.pm Cheers, d.
