Making this change should solve the issue...

Code:

$config['uri_protocol'] =
    (isset($_SERVER['HTTP_REFERER']) &&
     strpos($_SERVER['HTTP_REFERER'], 'apps.facebook.com') !== false) ?
         "PATH_INFO" : "REQUEST_URI";

$config['uri_protocol'] =
(isset($_SERVER['HTTP_REFERER']) &&
strpos($_SERVER['HTTP_REFERER'], 'apps.facebook.com') !== false) ?
"PATH_INFO" : "REQUEST_URI";

Applied this change. But the Result is same.

Now i am using php sdk version 3.1 can anyone send application libraries of php sdk version 2.2
