post message on facebook wall not working - php

Question

I want to post a message on facebook wall from our site. First I am getting error as
Uncaught OAuthException: (#200), when trying to post on wall
Now I am not getting the error but the code is not working.
$facebook = new Facebook(array(
'appId' => APP_ID,
'secret' => APP_SECRET,
'cookie' => true,
'req_perms' => 'email,read_stream,read_friendlists,publish_stream,offline_access,manage_pages',
));
$user = $facebook->getUser();
$token = $facebook->getAccessToken();
if ($user) {
try {
$user_profile = $facebook->api('/me');
} catch (FacebookApiException $e) {
error_log($e);
$user = null;
}
}
if (!empty($user_profile )) {
$username = $user_profile['name'];
$uid = $user_profile['id'];
try {
$post=$facebook->api("/".$uid."/feed", "post", array(
'access_token' => $token,
'message' => 'test',
));
} catch (FacebookApiException $e) {
error_log($e);
$user = null;
}
}
But no message is coming what to do? Is there any problem while creating the application?

Here's my wild guess, since our Comment Q&A wasn't going to work very well.
If you authorize your app with some set of permissions, and subsequently change the permissions that your app requests (at the app admin page), your existing authorization does not update to include the new permissions. Your app will still function, but the actions that require the new permissions will fail.
You can test if this is causing your error by simply removing the app from your personal account app settings page, and re-approving the app with the new permissions. If your problem vanishes, then congratulations. If not, you'll need to do more detective work. Your code appears to be fine.
