Just updated my restler 3 to release candidate 4 to try oAuth2 implementation. I've a restler 3 server and client, the server should offer an oAuth2.0 server and the client should implement oAuth2.0. But the oAuth2.0 client example index.php page stays empty. What did I wrong? I set all permissions recursively to 777 and installed any dependencies from composer (I'm new to composer). But the stuff got downloaded to restler's vendor folder so it's there.
Thank's for reading and answering. Jan
