here are a number of reasons why events or tickets are not visible in the ticket shop. In most cases, this is due to one of the settings below that are not set correctly:
Check whether the status of the event is Confirmed. Tickets cannot be sold for events whose status is Option, To Be Confirmed or Cancelled. Change the status to Events - Main.
Go to Events - Tickets and check if the settings are correct. Is the Online checkbox checked for the ticket you want to sell?
Verify that the sales period is set correctly. Click on Events - Tickets on 'Edit details' “behind” the Ticket type to go to the details window and check the 'Sales start' and 'Web sales end time'.
