Regarding my installation of Discourse, clicking register on the webpage has no response

Is the password long enough?

I'm stuck on the "Register Administrator Account" page and can't register

You might have ran into the same situation as I did. I experienced the same issue and tried whether creating an admin using rake would solve the issue. Only to find out that the password should be at least 15 characters. Please try whether filling in an admin password of 15+ characters solves it for you.
