You can only delete an event when it has no performances in it. We've written another article that explains how to delete performances.
If the Event has no performances, you can delete it by:
- Click on Events in the top navigation.
- Select the even you want to delete from the scroll pane on the left.
- In the middle box where the event details once sat, you should see a "Delete Event" button.
- Click that button, confirm the prompt, and the Event will be removed from your Event list.
