Answer 1

I had the same problem and I solved it.

First: Dont use &type=client_cred.

Second: Use the same URL everywhere!!!

My example:

My firs link:

FB login  

When I got the code:

$nexturl  = "https://graph.facebook.com/oauth/access_token?client_id=".$AppId."&redirect_uri=http://mysite.ru/ru/site_users.html?op=fbreg&client_secret=".$AppSec."&code=".$fbCode;
$response = @file_get_contents($nexturl);   
$params   = null;
parse_str($response, $params);
$graph_url = "https://graph.facebook.com/me?access_token=".$params['access_token'];
$arrResponse = json_decode(@file_get_contents($graph_url));

In $arrResponse i got all info about current user.

The value of URL should be the same everywhere. In the code and in https://developers.facebook.com/apps/.

In my case it is this: http://mysite.ru/ru/site_users.html?op=fbreg

The following are all incorrect using my example.

• http://mysite.ru/
• http://mysite/
• http://mysite/ru/site_users.html

Thats all. Very stupid problem. I solved it for three days :(
