Answered: Is q2a default "facebook-login" plugin working without any issue ?

Base off my comment, I got it to work by doing the following:

FILE A: /qa-plugin/facebook-login/qa-facebook-login.php
FILE B: /qa-plugin/facebook-login/qa-facebook-login-page.php

Open FILE A. On line 83 update the scope to this: 

scope=email,public_profile

Save.

Open FILE B. On line 59 update the me?fields=  to this

me?fields=email,name,verified,picture.width(250)

Save.

I didn't need to capture the user's location and other fields so this was enough for me.  All I really need is the email, name, and picture.  If you leave location as one of the permissions, you'll have to get your app approved by Facebook and that may take some time.
