Thanks Andy.
Yes. And no.
Your change appears to have fixed the booking so that it does create a booking and email the purchaser (though not the admin, which it did before, I think).
The booking is also recorded an the ticket available for download as PDF. (I don’t understand what the QR code does btw.)
However, it appears I can still only book one ticket per booking. Clicking the “Add Ticket” button does nothing…
And when I look on the dashboard, the number of tickets originally on sale is listed in the “Optional Custom Fields” column, and the number of tickets sold (i.e. 1 in my case) is listed in the “Quantity Available” column.
Hope this helps you fix it completely…
