Our company has been using Facebook's facebook.php and base_facebook.php files to auto-post entries to client's Facebook pages. Recently they have all stopped working and the only error we can get is an unexpected error has occured.
We cannot find a solution to this and we were wondering if anyone in the community has ran into this and can guide us in the right direction?
分享 That is because the token may have been expired. As the token is valid is just 2 hours after login.
You need to exchange your old token with a new one which has 60 day validity. The link exchange will be like this..
https://graph.facebook.com/oauth/access_token?
client_id=APP_ID& client_secret=APP_SECRET& grant_type=fb_exchange_token&fb_exchange_token=YOUR_OLD_ACCESS_TOKEN
The return response will be a 60-day validity token (something like below)
