Registration page not showing Username field

This just started happening, but the Username no longer appears on my Registration Form. I am a pro user. It only shows email, first name, and last name, then the captcha. When users hit Submit, it says that a Username is needed, but there is no field for one????

Thank you for reporting this important issue.

Your site gives the error that registration is disabled, so we’ll need you to either enable registration or give us a Dashboard login so we can take a look.
