Hello everyone, Everything seemed to be working right until I tried to send my newsletter to the 4,000+ recipients.
All my tests work fine, but when it's time to process to all my subscribers, this is what I get (see attachment)
I'm using AcyMailing 7.6.1 on Joomla 3.10.3
A blank pop-up that displays this message after a couple minutes.
What could be the issue?
Best Regards.
