Hi all!
 
The list of the requested parameters and fields from Dolphin to FB can be found in the file modules/boonex/facebook_connect/classes/BxFaceBookConnectConfig.php, see the folliwing lines:
 
$this -> aFaceBookReqParams = array(
            'scope' => getParam('bx_facebook_connect_extended_info') 
                ? 'email,public_profile,user_friends,user_birthday,user_about_me,user_hometown,user_location'
                : 'email,public_profile,user_friends',
            'redirect_uri' => $this -> sPageReciver,
        );
 
        $this -> sFaceBookFields = getParam('bx_facebook_connect_extended_info') 
            ? 'name,email,first_name,last_name,gender,birthday,bio,hometown,location'
            : 'name,email,first_name,last_name,gender';
 
If the parameter "Fetch Extended Profile Info (Facebook App Review Is Required)" in the m/facebook_connect/administration/ is enabled then Dolphin will request the "long" list of the fields and params.
