Answer 1

Your token has probably expired.

You can debug your token related issues on: https://developers.facebook.com/docs/facebook-login/guides/%20access-tokens/debugging

curl -i -X GET "https://graph.facebook.com/debug_token?
  input_token={input-token}&
  access_token={valid-access-token}

Running the above should return more info on your token. This should give you an idea on how to proceed. You can generate new tokens on the facebook developer page.
