I’ve been a happy users of this plugin for years, however starting two weeks ago when I send a new Newsletter the progress stays at 0 delivered. If I manually click the button in the WordPress menu for “Trigger the delivery engine” then only 16 messages get sent out. I have to manually click this button multiple times to deliver all 133 emails in my Subscriber list. Any help is appreciated. Thank you.
We have the same problem.
We use on differnet domains your Newsletter plugin.
Only Domains they update to WordPress 4.6x have the problem “The WordPress internal schedule is not triggered enough often”.
On Domains with WordPress 4.53 we didn’t have this problem.
If this a problem plugin<>Wordpress version?
The same but with WordPress version 4.53 and without PRO License
It show a “sheduler execution intervall mean” error too, but without the message “The WordPress internal schedule is not triggered enough often”.
I tested now to send a newsletter (with domain that have WordPress version 4.61) to 2150 subscriber.
Delivery speed is 400/hour
The delivery engine send in 15 min 99 emails.
I think this is ok.
But why I see in the upper part this message? I don’t know.
