[Mailman-Users] Cant make changes to lists

[Andreas Faye-Lund]

Hi

I have a serious problem with my mailman. When I try to make changes in 
the admin pages, the system just rejects any changes without any error 
messages. (Have checked for error messages in the apache and mailman logs).
The lists works for sending messages, but i cant add any users. Error 
appeared  after I changed the domain of the lists.
