Cant get token from janrain

[LuSterZ]

I set up the authentication window, according to the introduction janrain, but as the callback come, there is no token. What could be the problem? Here is the magic code:...\[code\]$rpxApiKey = '95c8d032db3db656e7716749552ff12c82f7108f'; if(isset($_POST['token'])) { echo "hello"; /* STEP 1: Extract token POST parameter */ $token = $_POST['token'];\[/code\]...but hello is not appearing.
