Check out the console to see if anything appears.

HERE'S THE CODE:

$(function(){
FB.init({ apiKey: '394416680606516', status: true });
 
FB.getLoginStatus(function(response) {
if (response.status === 'connected') {
console.log(response);
} else if (response.status === 'not_authorized') {
console.log('not connected to app');
} else {
console.log('not logged in to fb');
}
});
});
