Hi Tuan,

I have also a problem to delete events.
When I want to delete an event, I receive the message:
“Delete event (ID number of event) is not allowed because that event still has registrants. Please delete registrants of that event first before deleting the event” see attachment “Delete event_01.jpg”.
Ok let’s do that…after deleting the inscriptions …see “Delete event_02.jpg” and go back to events, I can’t still not delete the event, it’s come back with the same error.
In the event on frontend there are no participants…
Unpublished the event and still no possibility to delete the vent in backend.
