Tickets not working

Hi,

I installed the premium version and noticed that tickets are not working when trying to add some:
when I click the “Add ticket” button it show the good form, I fill it then click on “Create ticket“, it loads for a bit then nothing happens!

I tried to try the same think your admin demo site and it looks like working though
Demo link : https://awplife.com/demo/event-monster-premium-admin-demo/wp-admin/edit.php?post_type=awl_event_monster&page=em-tickets-page

BTW I’m using the version 3.0.2

Thanks for your help
