Pow: Robust, modular, extendable user authentication and management system

[danschultzer]

This will solve your issue: Pow.Phoenix.RegistrationController not available? · Issue #22 · pow-auth/pow · GitHub

You probably have the routes set up like this:

  scope "/", Powweb do
    pipe_through :browser

    pow_routes()
  end

You should remove the Powweb namespace so it looks like this:

  scope "/" do
    pipe_through :browser

    pow_routes()
  end
