I am creating a new calendar from a CSV file and it is quite complicated content. So I have needed to try the import, identify errors, correct them on the CSV file, delete the events, delete the calendar and then create the calendar again with the corrected CSV file.
Unfortunately having done this I still have errors to resolve and having deleted the events I get the error
Deleting this will create orphan events - delete the events first
when I try to delete the calendar.
I made sure that when managing the events I filtered for this specific calendar and had Hide Past Events set to No. I had emptied the trash as well.
How can I find what is linked to this calendar please?
