php - facebook redirect
I have a problem when using facebook authentication.
When the user accepted the app, it will redirect user to tab page(http://apps4you.hu), user wont stay on facebook, but only 1st time will do that if the user close and come back to app on facebook(already authenticated) it works fine in iframe. If I use the redirect_uri => my_app , it will redirect and redirect and redirect but never will work the app, the browser just loading and loanding but nothing happends. I spent days to fix this problem but I could not find any solution. Any idea whats wrong?
