Email Notifications Have Stopped

I believe this is the first post I have submitted in v5.1.6. The email notifications have stopped for sitewide users. Only the administrator is getting the email notifications.

This is for new posts and for re-sending posts.

While you troubleshoot, I have removed the cron job so a test post will not be sent to the end user, but should still be queued to the mail activities when the post is submitted. I also gave the 'support' user full access to post and doesn't require an approval from the administrator so you can troubleshoot. I typically have the super user 'z1naz' submit for approval and the administrator user 'samray48' approve the post, but that isn't working either. You should be able to approve your own post under the 'support' account for testing.

Again, I have temporarily disabled the cron job so your test posts will not go out to the end user and should only queue in mail activities once resolved. At this time, only the administrator notification is being queued and no sitewide users.

See attached screen shots. Please advise as soon as possible - I have a sitewide post 'May Newsletter' and 'Volunteers - Parking Lot Work' that I would like to send out to sitewide users as soon as possible.

Thanks!
