I would like some answers about this as well. I have a new Jomsocial site that I set up and have just had members join and start postijng in the community this poast week. Tonight I just figured out how to enable Emaiul digest, and since most of the users have't logged in for over 4 or 5 days, and I have the Email digest inactivity period set to 3 days, and the digest sent daily... I see about 10 jusers who are scheduled to receive the email digest in the pending list. I can preview them and they all look right, as far as the message stating how many days they have been inactive, and last so many posts.
Now when I run the cron manually, I can see it executes the task, but nothing moves from the email digest pending list, no emails are sent.
Here's the outpiut of the manually run CRON:
<messages>
<message>No videos pending for conversion.</message>
<message>No temporary videos to delete.</message>
<message>No files to transfer.</message>
<message>No Videos to transfer.</message>
<message>No avatars or cover of users needed to be transferred</message>
<message>No avatars or cover of groups needed to be transferred</message>
<message>No avatars or cover of events needed to be transferred</message>
<message>Removed Pending Invitation for Past Event</message>
</messages>
Should there also show an entry for email digests? Is there something else missing in my configuration that cron is not running the email digest queue? Or does it need to wait until so many hours have past since they got into the queue in the first place???
