Send Newsletter sends to only one subscriber
Tikiwiki V15
Throttle is 6 mails every 120 seconds
I send a newsletter every month to 200+ subscribers. It has been working fine until today.
When I try to send it gets sent to only one subscriber, the second in alphabetical order. The second attempt had identical results.
The only change has been the upgrade from V12.6 to V15.0.
Has anyone else had or not had newsletter sending problems with V15?
