I am getting a strange error with Devise on my Ruby on Rails app. When proceeding to the default Sign-Up form, after entering the email, and password field and then pressing sign-up, the button becomes unclickable and then nothing happens.
Previous Users have been successfully registered via this method, so I can confirm it did work previously. I have since not registered any new users in many months.
Heroku logs don't show any activity except for getting the sign-up page.
