Hi,
Thanks for using our plugins. I can help out here.
We are moving everyone over to Event Tickets Plus and have a new tutorial to move the ticket form:

We have this guide to moving to event tickets plus:
https://theeventscalendar.com/knowledgebase/moving-to-event-tickets-plus/
However, EDD Tickets will continue to work as is for now.
Are you still using just that? If so that guide will not work, but let me know and I can provide another snippet.
Thanks
