Hi Yves,
When I delete a booking in the back-end, the system in the front end keeps saying that I cannot book the event as I have already booked it...
When I checked the MySQL database in the Matukio_Bookings table, I noticed that my original booking was still present... So somewhere Matukio thinks it deleted the booking from the database, but it remains there.
Also, I just noticed that in the back-end under "Event Management -> Dates" it keeps saying that there are bookings for the event, but under "Event Management -> Bookings" there are no bookings displayed.
