[Mailman-Users] Missing pending requests in mailman database i.e no pending requests

[kibirango moses]

Hullo Users;
The administrator/moderator of the list gets a message saying that
there is a post pending approval. However, when he logs in and clicks
"Tend to pending moderator requests" there is nothing there. Basically
we keep getting "pending" notices but the queue is empty. It had been
working and no settings were changed.

When a message is sent to a mailing list there are no pending requests
but if sent to a list and some members of the list have the moderation
bit set as off they receive the message .

I am using mailman 2.1.13 on slackware linux 13

How can i solve this?
thanx in advance
