[Mailman-Users] Problems with Moderation

I am running mailman on OSX Lion.

Moderation through the web interface does not work.

If I try to do anything from the web interface (see screenshot) ... I can see a split second of it accessing the server, and the screen refreshes and goes back to this default of "defer"

Just no actions at all work.

Any idea where I should look ...

Thank you.
