I just made and sent a newsletter but then after some time a checked up on it and it said that 0 emails were sent.
Then after a long time of trying to figure out why the newsletter was not being sent, I finally noticed that there is a small message on the top of the screen when I am inside the Newsletter page that reads:
“The delivery engine is off (it should never be off). Deactivate and reactivate the plugin. Thank you.”
So I deactivated and reactivated the plugin and nothing happened. Also the message was still there.
p.s. on a side note – My humble suggestion is that message should be in a colored box or something so people will notice it.
usually that happens when newsletter cannot add a scheduled plan to wordpress.
If you can install my free diagnostic plugin from the download area, you should be able to see the schedules listed under the “cron” panel. Can you report them to me?
I am having this issue also. There is a message saying “The delivery engine is off (it should never be off). See the System Check below to reactivate it.”
When I click “Trigger the delivery engine” it sends 16 emails, but that’s it. How do I reactivate the delivery engine and why is it off? The information you provided in this post is unclear to me. How do I keep the cron system working correctly?
