title: Laravel Controller can't receive POST method. Is the "areas" reserved word by any chance?
body: <p>[ErrorException Undefined index: available_areas] happens.
  Somehow Other variables are ok.
  I am not sure why available_areas isn't sent.
  POST Data is sent to register function of RegistersUsers.</p>
