I have a Facebook Account (Lets call him Admin), a Page, and an Application... I have problems to obtain extended token for a Server Script to post in Page's Wall. In a lot of tutorials, they recommends to call this URL:
https://graph.facebook.com/oauth/authorize?client_id=[APP_ID]&scope=manage_pages,publish_stream&redirect_uri=http://www.facebook.com/connect/login_success.html
I login with the Facebook account, apply the permissions, but instead of give me the code/token, I got a page with this:
Success ADVERTENCIA DE SEGURIDAD: trata la dirección URL como si fuera tu contraseña y no la compartas con nadie.
With font red... I've tried with 3 browsers, but same results. What I'm doing wrong? Do you know a good (and updated) tutorial?
