Update: I was using PHP 7.0.0
Switching to 5.6.1 seems to have solved the problem.
I’m running into the same issue. Can’t save any events. Just did a clean WP install with default theme, and latest version of Events Manager 5.6.2. This is the error I get:
Your event details are incorrect and cannot be published, please correct these errors first:
Missing fields: ticket_name.
There was a problem saving the ticket.
