Facebook platform is really not friendly with IEs browsers and I'm sure that a lot of developers have many difficulties in IE while working with Facebook.
Recently I've faced a troubles in IE7 and IE8 while calling method FB.login();
Authentication popup appears but after that security error popup is shown with text like:
Message: Permission denied
Line: 22
Char: 4250
Code: 0
URI: https://connect.facebook.net/en_US/all.js
In other browsers everything works fine.
There is a hack that allows to avoid this error in IE. It is necessary to add some piece of code after calling FB.init() on client side:
FB.init({
appId: 'xxxxx',
appSecret: 'xxxxxxxxx',
status: true
cookie: true
});
// this code solves the issue
FB.UIServer.setLoadedNode = function (a, b) {
FB.UIServer._loadedNodes[a.id] = b;
};
The trouble is described in Facebook Bugzilla: http://bugs.developers.facebook.net/show_bug.cgi?id=20168
Hope, it will be fixed by Facebook soon.
