Facebook Login Not working - recenty

Hi All,

I have used Facebook Login in my Titanium App, It was works fine until last week. But for the last two days I am getting error while new user Login with Facebook.

Facebook Login Error Screen

Also I did followed the below thread http://developer.appcelerator.com/question/139217/facebook-login-not-working-today

Modified my Facebook app's advanced settings and set the Authentication to native/desktop

But still I am getting the Error.

Is there any configuration need at http://developers.facebook.com/?

Here Is my sample code

Titanium.Facebook.appid = "xxxxxxxxxxx"; //Production
Titanium.Facebook.permissions = ['publish_stream', 'read_stream', 'email', 'user_about_me'];
 
var fbSignupBtn = Ti.UI.createButton({
    title: "Login with Facebook",
    width: 160,
    left: 10,
    top: 25
});
win.add(fbSignupBtn);
 
fbSignupBtn.addEventListener('click', function () {
    Titanium.Facebook.authorize();
});
 
Titanium.Facebook.addEventListener('login', function (e) {
    if (e.success) {
        //some actions here
    } else if (e.error) {
        alert("Error = " + e.error);
    } else if (e.cancelled) {
        alert("canceld");
    }
});

I am using Titanium 2.1.1. Thanks in Advance

am using this code in 2 programs and they are working fine

Titanium.Facebook.appid = "xxxxxxxxxxxxxxxx";
        Titanium.Facebook.permissions = ['publish_stream'];
 
        var share = Ti.UI.createButton({
            backgroundImage : 'fb_share.png',
            height : '42',
            width : '122',
            top : 10,
            left : 10,
            link : images[n].link,
        });
 
        share.addEventListener('click', function(e) {
            if (!Ti.Facebook.loggedIn) {
                var sourceLink = e.source.link;
                Ti.Facebook.addEventListener('login', function(e) {
                    if (e.success) {
                        fbSharing(sourceLink);
                    } else if (e.error) {
                        alert(e.error);
                    } else if (e.cancelled) {
                        alert("Canceled");
                    }
                });
                Ti.Facebook.authorize();
            } else {
                fbSharing(e.source.link);
            }
        });

and here is the source of fbSharing function

var fbSharing = function(link) {
 
    var resultNotification = Ti.UI.createNotification({
        message : 'sharing_done',
        duration : Ti.UI.NOTIFICATION_DURATION_LONG
    });
    Ti.Facebook.request('links.post', {
        url : link
    }, function(e) {
        if (e.success) {
            resultNotification.message = 'sharing_done';
            resultNotification.show();
        } else {
            resultNotification.message = 'sharing_error';
            resultNotification.show();
        }
    });
}
