问题
I have a sample app that has a 'Like' button. It works before but now it doesn't. I've tested this on jsfiddle.net before and it works too. But after I've uploaded my files on a server it has a bug. The 'Like' button pops up and then has this error:

I've already read this article on SO already and followed the answer but still didn't work. Any views on this error?
PS: I am all in all fairly new to this.
and here's the sample code I'm using:
<?php
include_once("../incs/dbcon.php");
require_once('AppInfo.php');
require_once('utils.php');
require_once('../sdk/src/facebook.php');
//This gets the signed_request from FB which checks the 'liked' status on the current page
$signed_request = $_REQUEST["signed_request"];
list($encoded_sig, $payload) = explode('.', $signed_request, 2);
$data = json_decode(base64_decode(strtr($payload, '-_', '+/')), true);
$app_data = isset($data["app_data"]) ? $data["app_data"] : '';
$_REQUEST["fb_page_id"] = $data["page"]["id"];
$access_admin = $data["page"]["admin"] == 1;
$has_liked = $data["page"]["liked"] == 1;
$facebook = new Facebook(array(
'appId' => AppInfo::appID(),
'secret' => AppInfo::appSecret(),
));
$user_id = $facebook->getUser();
if ($user_id) {
try {
// Fetch the viewer's basic information
$basic = $facebook->api('/me');
} catch (FacebookApiException $e) {
// If the call fails we check if we still have a user. The user will be
// cleared if the error is because of an invalid accesstoken
if (!$facebook->getUser()) {
header('Location: '. AppInfo::getUrl($_SERVER['REQUEST_URI']));
exit();
}
}
// This fetches some things that you like . 'limit=*" only returns * values.
// To see the format of the data you are retrieving, use the "Graph API
// Explorer" which is at https://developers.facebook.com/tools/explorer/
$likes = idx($facebook->api('/me/likes?limit=4'), 'data', array());
// This fetches 4 of your friends.
$friends = idx($facebook->api('/me/friends?limit=4'), 'data', array());
// And this returns 16 of your photos.
$photos = idx($facebook->api('/me/photos?limit=16'), 'data', array());
// Here is an example of a FQL call that fetches all of your friends that are
// using this app
$app_using_friends = $facebook->api(array(
'method' => 'fql.query',
'query' => 'SELECT uid, name FROM user WHERE uid IN(SELECT uid2 FROM friend WHERE uid1 = me()) AND is_app_user = 1'
));
}
// Fetch the basic info of the app that they are using
$app_info = $facebook->api('/'. AppInfo::appID());
$app_name = idx($app_info, 'name', '');

回答1:
This message is what Facebook use to stop Like-jacking and prevent spam. It can also appear if the Like button has been added to a website / domain for the first time. Give it time and the message will disappear once Facebook is satisfied that your site isn't doing any of the above things.
