I am trying to experiment with the new facebook authentication system, and I can't getthe login to work.
I'm getting the following error message:
API Error Code: 100
API Error Description: Invalid parameter
Error Message: next is not owned by the application.
The url that is being sent to facebook is:
http://www.facebook.com/connect/uiserver.php?app_id=444444444444444&next=http%3A%2F%2Fstatic.ak.fbcdn.net%2Fconnect%2Fxd_proxy.php%23%3F%3D%26cb%3Df357eceb0361a8a%26origin%3Dhttp%253A%252F%252Fwww.mysite.com%252Ff38fea4f9ea573%26relation%3Dopener%26transport%3Dpostmessage%26frame%3Df23b800f8a78%26result%3DxxRESULTTOKENxx&display=popup&channel=http%3A%2F%2Fwww.mysite.com%2Ffbtester.php&cancel=http%3A%2F%2Fstatic.ak.fbcdn.net%2Fconnect%2Fxd_proxy.php%23%3F%3D%26cb%3Df6095a98598be8%26origin%3Dhttp%253A%252F%252Fwww.mysite.com%252Ff38fea4f9ea573%26relation%3Dopener%26transport%3Dpostmessage%26frame%3Df23b800f8a78%26result%3DxxRESULTTOKENxx&locale=en_US&return_session=1&session_version=3&fbconnect=1&canvas=0&legacy_return=1&method=permissions.request
Note that the 'Next' variable in the url is:
next=http%3A%2F%2Fstatic.ak.fbcdn.net%2Fconnect%2Fxd_proxy.php%23%3F%3D%26cb%3Df357eceb0361a8a%26origin%3Dhttp%253A%252F%252Fwww.mysite.com%252Ff38fea4f9ea573%26relation%3Dopener%26transport%3Dpostmessage%26frame%3Df23b800f8a78%26result%3DxxRESULTTOKENxx
Any ideas what could be going wrong? All I've done is copy and paste the facebook login demo code from facebook's website:
<?php
define('FACEBOOK_APP_ID', 'your application id');
define('FACEBOOK_SECRET', 'your application secret');
function get_facebook_cookie($app_id, $application_secret) {
$args = array();
parse_str(trim($_COOKIE['fbs_' . $app_id], '\\"'), $args);
ksort($args);
$payload = '';
foreach ($args as $key => $value) {
if ($key != 'sig') {
$payload .= $key . '=' . $value;
}
}
if (md5($payload . $application_secret) != $args['sig']) {
return null;
}
return $args;
}
$cookie = get_facebook_cookie(FACEBOOK_APP_ID, FACEBOOK_SECRET);
?>
<!DOCTYPE html>

<script>
FB.init({appId: '<?= FACEBOOK_APP_ID ?>', status: true,
cookie: true, xfbml: true});
FB.Event.subscribe('auth.login', function(response) {
window.location.reload();
});
</script>
</body>
</html>
Thanks for the help!

Try refreshing your browser or reopening the site; on a mobile app, close and reopen the app. You can also check to see if Facebook is offline and then restart your device, update apps, and clear your cache.
If you're having trouble logging into your Facebook account from your Facebook app: Make sure that you have the latest version of the Facebook app, or delete the app and then reinstall it. Try logging in from a mobile browser (example: Safari, Chrome).
Fix 1: Clear Facebook's cache To clear cache on an Android device, open the Settings app > Apps > Facebook > Storage > Clear Cache > Clear Data > re-open Facebook.
I was getting the same error, but I am using Rails and the problem was the Connect URL was not updated. My local application is running on port 3000, and the Connect URL was pointing at port 80.
See if changing that works for you.
Connect tab on the leftConnect URL is setup correctly
