Hi!
Users authenticate normally on my iPhone app, and the permission for publish_stream is requested correctly. When the user want to post something on his wall, the text is transmitted to my backend and the backend posts it (with the transmitted session key) to the users facebook wall. The first post is always possible but at the second, the response is:
"The user hasn't authorized the application to perform this action"
But I was already able to post some seconds ago. What is wrong?
Best Steve
