Cannot submit event registration for free ticket
Overview My event registration and payment form suddenly stopped working for the complimentary/free ticket option. Users cannot press "continue" to submit the form if they chose complimentary ticket.
Event registration page: click here
Before It was working fine and we registered a bunch of complimentary ticket users until it suddenly stopped working.
After When you click the submit button, the next page does not load and it stays on the current page, i.e. folks cannot register.
