Hi hi,
For my charity’s past 2 mailouts, the open rate has dropped from 50% to 9%. And I am not receiving the newsletter to my 3 accounts.
There’s been no change anywhere on the site. I’ve looked at the logs but I can’t see anything. I sent the second newsletter today (23 September) but the last log is 17 September, and says “17-09-2025 02:25:22 – FATAL – 8.9.4 – 15.1 MB/256 MB – [cron] > Delivery engine lock already set: can be due to concurrente executions or fatal error during delivery”.
I know 1 person received the email. It can’t be the system measurements, because I didn’t receive any email to my 3 accounts. There’s nothing in any of my junk folders.
Help!
Oliver
