I copied the whole of the example.php in the Facebook php sdk at the exmaples folder to another php file and i got this error: Fatal error: Uncaught OAuthException: Invalid OAuth access token signature. thrown in C:\wamp\www\facebook-php-sdk-4ea94b9\src\base_facebook.php on line 1039 .
When i comment this line: $naitik = $facebook->api('/naitik'); . Everything seems to be quite fine except this error: Notice: Undefined variable: naitik in C:\wamp\www\facebook-php-sdk-4ea94b9\examples\newExample.php on line 100 . Which is expected. What could be the problem?
