Hi Yves
I upgraded the 2.1.3 version to 2.1.7 (using the upgrade function of matukio)
When I add a booking by a organiser (frontend) I get the same error again
This means that version 2.1.7 does not adapt the database to the new fields
(can you please include this in a new relaese or give me the link to the correct table structure ?)
