After recently setting up a forum I have been trying to work out why the digest/summary emails aren’t being sent.
I have tried to see what the digest email looks like under Admin>Emails>Preview Summary but all it is is a blank screen.
Have you created any topics, etc on your forum this week?
Mine is also blank on my test site if I leave the default parameters in (last seen: 21/01/22, user: JammyDodger) as I haven’t had any new topics/actions/etc this week. However, if I select 21/12/21 as the ‘last seen’ date, then it populates a summary email for me as it has something to show me.
