My Register Page Has No Register Button

All Registration Buttons, including the default 'Register' button must be toggled ON from the Web Page tab before they appear on your event’s registration page.

To check, go to Web Page: you will see list of all Registration Buttons: all those checked 'ON' will appear on your event Web Page. 

This feature is so that you can create event web pages before you allow registrations, or so you can remove the basic Register button (toggle OFF) and replace it with ticket(s) or other Registration Buttons instead.

(Note: The Register Button is toggled ON by default.)
