I have set up scheduled reminder emails for events, but they do not seem to go out. I tested it by signing up for an event myself and did not receive a reminder email. Anyone got any idea on what I'm doing wrong?
Have you enabled the Send Scheduled Reminders scheduled job? You can check by going to Administer > System Settings > Scheduled Jobs. Scroll down to Send Scheduled Reminders and ensure that the Enabled? box is set to Yes.
You'll also need to ensure that you have a cron job enabled for your Civi installation.
We had the same problem - it was due to the developers setting the cron job to only run once per day at midnight (not very useful for timely responses!)
