FB.getLoginStatus returns status unknown
When calling FB.getLoginStatus using a valid Facebook App the response status is always unknown. Exact response is {authResponse: undefined, status: "unknown"}.
<html>
<body>
<div id="fb-root"></div>
<script>
window.fbAsyncInit = function(){
FB.init({ appId:'1484134468466778', status:true, cookie:true, xfbml:true});
FB.getLoginStatus(function(response){
console.log(response);
});
};
(function(d){
var js, id = 'facebook-jssdk'; if (d.getElementById(id)) {return;}
js = d.createElement('script'); js.id = id; js.async = true;
js.src = "//connect.facebook.net/en_US/all.js";
d.getElementsByTagName('head')[0].appendChild(js);
}(document));
</script>
</body>
</html>

Answer
This was happening for me in Chrome, and was because Chrome was configured to block third-party cookies and data.
Once I made that configuration change, FaceBook is able to log me into my app without a problem.
- Chrome Settings
- Show advanced settings...
- Privacy
- Content settings...
- uncheck Block third-party cookies and site data
