I wrote a simple php code to utilize the file upload API. It works on one PC but returns a ""Please provide the access_token param." error on another even if it it was just generated a few seconds ago and is included. That's why I'm sure that the server side is okay, but I can't figure out what the difference between to machine is. I'm not sure where to start. Any idea about the possible cause?
