I've changed the file "C:/OTRS/Kernel/System/Web/InterfaceCustomer.pm" as like below: (plz notice that I have a Window server, if you use linux or unix, the path of the file will not be C:/OTRS/........etc.) In Kernel/System/Web/InterfaceCustomer.pm you can find the following line: $Self->{GroupObject} = Kernel::System::CustomerGroup->new(%{$Self}); Change it to: $Self->{CustomerGroupObject} = Kernel::System::CustomerGroup->new(%{$Self}); Cordiali saluti Best regards Luca Martella luca.martella@unilabsrl.it 2007-05-25 [ # ] { @ }
