Does the latest plugin code not work with moodle 2.8? I migrated to a new server (painful) to see if that would help the spamming of event reminders. It did not. I upgraded to moodle 2.8 and got the latest event reminder code (1.4) and it stopped working altogether.
Does email reminders version 1.4 not work with moodle 2.8? I'll stop trying to debug if that is the case.
