Facebook app is misconfigured

Question

I am working on a facebook app, it takes the oauth from the user. Everything works fine but, When the user reject the popup oauth then it displays:

"Sorry, the details for F_wp_app cannot be displayed because the app is misconfigured."

Here is the code for my index.php file

include_once 'facebook.php';

$user = $facebook->getUser();

if($user)
{
    define('WP_USE_THEMES', true);

/** Loads the WordPress Environment and Template */
    require('./wp-blog-header.php');
    ob_end_flush();
}
else
{
    $loginUrl = $facebook->getLoginUrl(array(
    'scope'=>'publish_stream',
    'redirect_uri'=>'https://apps.facebook.com/226166417548050/'
    ));
    echo "<script> top.location='$loginUrl'</script>";
}

I want that if the user rejects the oauth then it is automatically redirected back to the oauth.

Any help would be appreciated. Thankyou
