[Mailman-Users] Error when editing user

[Jeff Conley]

We've had several user's email accounts get hacked, and spam get sent
out to the entire list.

When this happened before, I would simply check their moderation bit
and could hold messages until I was assured their account was secured.

I tried to do this yesterday, and began receiving the below error
message. I also receive it when I try to set the global moderation
bit.

Any help would be greatly appreciated!
