Refused to display 'https://www.facebook.com/home.php' in a frame because it set 'X-Frame-Options' to 'DENY'.

Refused to display 'https://www.facebook.com/home.php' in a frame because it set 'X-Frame-Options' to 'DENY'., someone asked me to explain?

I am using Facebook authentication API, I got the following error “Refused to display in a frame because it set 'X-Frame-Options' to 'DENY.'”, Failed to logout from Facebook.

Add your url of your website in facebook app

When I click the Facebook sign out button, I got an error message in the developer console of the browser and it fails me to log out from fb.

My code:

        // Loadthe SDK Asynchronously
        (function (d) {
            var js, id = 'facebook-jssdk', ref = d.getElementsByTagName('script')[0];
            if (d.getElementById(id)) { return; }
            js = d.createElement('script'); js.id = id; js.async= true;
            js.src = "//connect.facebook.net/en_US/all.js";
        // Initthe SDK upon load
        window.fbAsyncInit = function () {
                appId: '1693135087593940', // App ID
                channelUrl: '//' + window.location.hostname +'/channel', // Path to your Channel File
                status: true, // check login status
                cookie: true, // enable cookies to allow the server to access thesession
                xfbml: true  // parseXFBML
             //listen for and handle auth.statusChange events
            FB.Event.subscribe('auth.statusChange', function (response) {
                if (response.authResponse) {
                    // user has auth'd your app and is logged into Facebook
                    //FB.api('/me', function (me) {
                    FB.api('/me', 'get', { access_token:response.authResponse.accessToken, fields: 'id,name,gender,email' }, function (me) {
                        if (me.name) {
                           document.getElementById('auth-displayname').innerHTML = me.name;                          
                    document.getElementById('auth-loggedout').style.display= 'none';
                    document.getElementById('auth-loggedin').style.display= 'block';
                } else {
                    // user has not auth'd your app, or is not logged intoFacebook
                    document.getElementById('auth-loggedout').style.display= 'block';
                    document.getElementById('auth-loggedin').style.display= 'none';
            $("#auth-loginlink").click(function () { FB.login(); });
            $("#auth-logoutlink").click(function () { FB.logout(function () { window.location.reload(); }); });
    <h1>Facebook Login Authentication Example</h1>
    <div id="auth-status">
        <div id="auth-loggedout">
            <a href="#" id="auth-loginlink">
                <img src="/Images/fconnect.png" style="border: 0px" /></a>
        <div id="auth-loggedin" style="display: none">
            Hi, <span id="auth-displayname"></span>(<a href="#" id="auth-logoutlink">logout</a>)
