Good evening and welcome to the Events Calendar Support forum!
Thank you for reaching out to us.
We are sorry to hear about the tickets no longer displaying. Yikes!
I would love to help you with this topic.
Would it be possible to get a screenshot of the “Edit Event” screen ?
More specifically, I am interested in the start and end sale date of your tickets (you will need to click on “Edit ticket” for that).
Typically when tickets do not appear, it means that there start sale date has not yet been met OR that the event is in the past.
The usual cure is to remove the event start sale date.
Hang in there!
