[Mailman-Users] Mailman administraive interface does not store data

[Eggert Ehmke (FTV)]

Hello,

I already run a Mailman list on my server that works fine. Now I set up a 
second list on another virtual domain. All looks fine, aliases and 
virtual-mailman are configured, the apache is configured. I can access the 
list administration but cannot change the general options. When I enter data 
in the general options and press Submit, the old options are displayed again. 
What makes things bad, I don't see any related error messages, also not in 
apache log files. How to track this down?
