Several years ago I had received help via this forum to have the Promo Code addon only allow the codes to be applied to “Regular” tickets. The final solution created and is visible near the bottom of this thread: https://eventespresso.com/topic/promo-code-for-specific-ticket-types/
Unfortunately, this has stopped working as intended and it is allowing the Promo Codes to be used on any ticket type. We have not made any changes to this code (used in a plugin) since we implemented it.
Can you point me in the right direction to see why the ticket filter is no longer grabbing just “Regular” tickets?
Sorry, I realize that I misrepresented the problem. It is no longer allowing the promo codes to work on “Regular” tickets. We are labelling the ticket names the same as always but the codes no longer work as expected.
