Hello! I faced an error last friday...
I followed all the instructions to create the facebook application, used correctly app ID and Secret, and created the token with my user, as usual. But last friday, I logged off my facebook account, and then the problem started. As soon as I logged off, the "sharing in facebook" option inside my K2 item had disappeared (no page name anymore and evenno auto posting)
I made all the proccess again, with the previous app, and couldn't generate the token, as I received an error as it follows:
{"error_code":12,"error_msg":"REST API is deprecated for versions v2.1 and higher (12)","request_args":[{"key":"api_key","value":"466844007396038"},{"key":"credentials_type","value":"password"},{"key":"email","value":"lucas.melo.nascimento.ln\u0040gmail.com"},{"key":"format","value":"JSON"},{"key":"generate_machine_id","value":"1"},{"key":"generate_session_cookies","value":"1"},{"key":"locale","value":"en_US"},{"key":"method","value":"auth.login"},{"key":"password","value":"--sanitized--"},{"key":"return_ssl_resources","value":"0"},{"key":"v","value":"1.0"},{"key":"sig","value":"dc2ecd6f3574c9daec22499cb521b47a"}]}
This happening, I just can't create the access token, what doensn't allow me to save my facebook user settings, and consequently, no posts shared on facebook.
Just to highlight, in my facebook application I only can use the v3.3 APIs, so I don't understand why the error message above, from a minute to another.
Please, I need your help a lot!!
