The last sent digests were on 3. January, since then no one more has been sent out automatically.
In the log I only see digest emails created manually by me.
Every other kind of automatic generated email work perfectly (mailing list, user mentioned, sign in by email, …).
There are no queued job in Sidekiq. I manually triggered Jobs::EnqueueDigestEmails with no results. The job starts and ends after few milliseconds, like it has nothing to process.
This morning I noticed this warning in admin/logs/Error logs I don’t know if it could be related to the digest issue:
It’s quite obvious, but let me suggest to put a little additional note in the setting description like (setting this ON will disable digest emails for all users). If set to ON I would also disable the Activity Summary feature in the user preference for all users, because it won’t work.
