[Plugin ZM-ajax login register]

Why will this plugin not pull the users info from facebook if they use facebook to login=, I think it has to do with in this code but not sure

* Maps our FB response fields to the correct user fields as found in wp_update_user. Then
* calls setUpNewFacebookUser, and passes the correct response via JSON to JS.
*
* @since 2.0.0
*
* @return JSON A JSON object
