Thanks Scott for fixing the Login. (It was because I was missing the facebook, google. Thankfully your screenshot pointed out in the right direction. I will check with the real device and update whether I am able to register/ login.
For the CORS error on iOS should I msg in this thread or the other. Please respond to that as well. I sincerely appreciate your help.
Can you also point to the file that I should edit if I want to remove something from the menu.
