[Mailman-Users] Moderation commands not working

Hi,

i have a problem with a pending moderation request. Whenever i chose one of the four options for the pending email and submit the form, the page reloads and is still showing this email as pending. I did not find anything valuable in the log files, but i executed a check_perms to see if mailman can't moderate this email because of a filesystem permission problem. I don't know where to search for the bug, so i hope, anyone around here could help me.

Thank you very much in advance.

Simon
