I installed and configured the newsletter plugin, everything went fine except the sending. I read the guide about ‘The Delivery Engine Speed’ and set the PHP execution timeout in my Plesk Panel, but nothing changed in the Diagnostics psge the value is still:
– Scheduler execution interval mean 2027 seconds (KO)
I also set an external CronJob every 5 minutes… what should I do next?
The average time relies on 300 samples, so with a cronjob active you should wait enough time to get the new average value. The external cron should adjust the problem but you need to check if that call works correctly.
