    FB.api('/me/feed', 'post', { message: body }, function(response) 
    { 
        if (!response || response.error)

I'd suggest alerting the response.error instead of the static string, or set a debugger; point there and look at the value.

Also look at the network traffic and check out the response stream if those don't work.

To post to a wall even after the user left your app (but still left the permissions accepted for publish_stream), then you can just user your app id/secret to post as them. From https://developers.facebook.com/docs/reference/api/permissions/

Enables your app to post content, comments, and likes to a user's stream and to the streams of the user's friends. With this permission, you can publish content to a user's feed at any time, without requiring offline_access. However, please note that Facebook recommends a user-initiated sharing model.
