[Mailman-Users] Digest mode sending individual emails

[ml lists]

Hello,

I am having some problems with a mailman list that i administer.   The list
is configured to send digest emails once a week (via the web ui) but this
is not happening, instead emails are being sent individually, as they are
posted to the list, but tagged as digest.

Would anyone have any suggestion how to fix this so they are sent weekly?

I'm running Ubuntu 11.10 and mailman 2.1.14-1
