After moving a website of a friend from one server to another, his newsletter plugin didn’t work anymore. It sent out the test mails, but it was refusing to send out the mails to the subscribers.
He is using a quite good free (if you don’t need the PRO functionality) newsletter plugin for wordpress.
After a little bit of searching we found out that on the email section within the plugin there is a message saying: “Delivery engine next run” and a negative count.
This is due to wp-cron.php and just deactivating and activating the plugin solves the issue. After that Deliver engine next run had a positive value.
thank you very much! it saved my time….
it works! thanks alot !
