New Facebook API issue

Can anyone help me with this code and tell me what is wrong?

My code is not working anymore with the new Facebook API and I am getting the below errors!

Uncaught Error: OAuth2 specification states that 'perms' should now be called 
'scope'. Please update.

Error is in http://connect.facebook.net/en_US/all.js line 23

And even if I changed it, it still does not work at all!

//THIS FUNCTION WILL INITIALIZE THE FACEBOOK API AND WILL ADD NEW FACEBOOK ACCOUNTS.
var apikey = $("#apikey").val();
//var tuittingID = $("#tuittingID").val();
FB.init({ apiKey: apikey, status : true, cookie : true, oauth: true });
FB.getLoginStatus(handleSessionResponse);
$('#FBlogin').live('click', function() {
    FB.login(handleSessionResponse, {
        scope:'manage_pages, publish_stream, offline_access, user_status, 
        read_insights'
    });
    return false;
});
function handleSessionResponse(response) {
    if (!response.session || String(response.scope) == '') {
        return;
    }
    else
    var tuittingID = $.cookie("tuittingID");
    $('#AccessToken').val(response.session.access_token);
    $("#loader").show();
    $.post("tuitting/facebook_lib/fbadd.php",
    { tuittingID: tuittingID, uid: FB.getSession().uid, usid: 
    FB.getSession().session_key, accesstoken: response.session.access_token },
    function(data){
        reloadAccounts();
        $("#loader").hide();
        FB.logout(function(response) {
        }); //END LOGOUT FROM FACEBOOK AFTER SUCCESSFULL ACTION
    }
    ); //END AJAX POST FUNCTION DATA
}

Did you make the changes needed to support Oauth 2? it's been mandatory since Oct 1st but the SDKs were only forced onto Oauth 2 yesterday (December 13 2012)

See https://developers.facebook.com/docs/oauth2-https-migration/ - there's a summary of what changed and links to the announcing blog posts - the authentication and javascript docs are the docs you're most likely to need to check if you're making changes as this is where the changes were

This is the Oauth 1.0 code:

html

<div id="fb-root"></div>
<div class="fb-login-button" scope="email,user_birthday" 
onlogin="afterFacebookConnect();" autologoutlink="false">Login con Facebook</div>

javascript

        window.fbAsyncInit = function () {
            FB.init({
                appId: 'id_of_app',
                status: true,
                cookie: true,
                xfbml: true                });
        };


        if (document.getElementById('fb-root') != undefined) {
            var e = document.createElement('script');
            e.type = 'text/javascript';
            e.src = document.location.protocol + '//connect.facebook.net/es_ES/all.js';
            e.async = true;
            document.getElementById('fb-root').appendChild(e);
        }


function afterFacebookConnect() {
    FB.getLoginStatus(function (response) {
        if (response.session) {
            window.location = "/facebook/login?token=" + response.session.accessToken;
        } else {
            // user clicked Cancel
        }
    });
}

Changes I made to adapt to Oauth 2.0:

   window.fbAsyncInit = function () {
        FB.init({
            appId: 'id_of_app',
            status: true,
            cookie: true,
            xfbml: true,
            oauth:true // additional parameter
        });
    };

function afterFacebookConnect() {
    FB.getLoginStatus(function (response) {
        if (response.authResponse) {
            window.location = "/facebook/login?token=" 
           + response.authResponse.accessToken;
        } else {
            // user clicked Cancel
        }
    });
}

Additional: Here is the code that handles the response (ASP.NET MVC, C#):

using Newtonsoft.Json.Linq;

   [RequireHttps]
    public ActionResult login(string token)
    {
        WebClient client = new WebClient();

            string JsonResult = client.DownloadString(string.Concat(
                   "https://graph.facebook.com/me?access_token=", token));
            JObject jsonUserInfo = JObject.Parse(JsonResult);

            string nombre = jsonUserInfo.Value<string>("first_name");
            string segundo_apellido = jsonUserInfo.Value<string>("last_name");
            string nombre_completo = jsonUserInfo.Value<string>("name");
            string genero = jsonUserInfo.Value<string>("gender");
            string email = jsonUserInfo.Value<string>("email");
            string birthday = jsonUserInfo.Value<string>("birthday");

    // here you do your logic to login the user 
    // otherwise you can send user to the registration 
    // form and fill in some data you received from facebook

    }

We were also affected by this change and we made the following changes to make it work. FB.init() was required as coded below with oauth set as true.

        FB.init({
        appId: 1234567890123,
        oauth: true
    })

And now there is no more session, response.session becomes response.authResponse and response.session.uid becomes response.authResponse.userID

            FB.login(function(response) {
        if (response.authResponse) {
                var postData = {
                    FBID: response.authResponse.userID,
                    Access_Token: response.authResponse.accessToken
                };

Also make sure you're using FB.getAuthResponse() instead of FB.getSession().
