Good evening Fernando and welcome back!
Thank you for reaching out to us.
We are sorry to hear about the tickets disappearing on you.
I would love to help you with this topic.
When something like this happens, it is usually because of one of the following reasons:
- Tickets are out of stock: the solution is to validate the capacity (stock) for that ticket and it’s WooCommerce stock as well.
- Ticket start sale or end sale date: make sure these settings are correct. If the start sale date is not met, tickets do not appear. If the end sale date is met, the ticket disappear. I recommend examining your tickets for such dates. You can remove them temporarily if needed.
Let me know how that goes.
Best regards,
Geoff B.
