[Mailman-Users] Moderator request(s) waiting but ... nothing to moderate

[Manuel Vacelet]

Hello,

One of my list admin is asked to moderate pending emails on daily
basis with a mail like:
> The listname at lists.server.com mailing list has 2
> request(s) waiting for your consideration at:
>
>	https://lists.server.com/mailman/admindb/listname
>	
> Please attend to this at your earliest convenience.  This notice of
> pending requests, if any, will be sent out daily.

But when he goes on the given url there is nothing to validate just
the following message:
> Database Updated...
> listname Administrative Database
> There are no pending requests. Click here to reload this page.

but the day after, the very same message is still sent by mailman.

Any idea of what happens ?

Manuel
