Error validating access token


Just in time for the launch of a new web-site, the facebook access token was about to expire.According to facebook in an hour, the facebook_wall module actually showed a negative number (see attached). Also, in response to certain events that are security-related, access tokens may be invalidated before the expected expiration time. Unless you have persisted the expiry time passed to your App along with the access token, your app may only learn that a given token has become invalid is when you attempt to make a request to the API. Post("/FB Fan page ID/feed", parameters); } } Hi, Facebook doesn't notify you that a previously issued access token has become invalid. Index Of("=") - 1)); } string access_token = "Long Lived Access Token"; var client = new Facebook Client(access_token); dynamic parameters = new Expando Object(); parameters.message = "xxxxxxxxxxxxxxxxxxxxxxxx"; = "XXXXXXXXXXXX"; parameters.picture = "XXXXXXXXXXXXXXXXX"; = "XXXXXXXXXXXXXXX"; parameters.caption = "XXXXXXXXXXX"; client. In each case, the API will return an HTTP 400 status code, a code and a subcode in a JSON body explaining the nature of the error.

I am trying to post on my Facebook fan page using Facebooh Graph API. I was able to post my contents on Facebook, but the moment I logged out from administrator account and tried posting the contents on my Fan Page I am getting this error. To get Extended Page Access token I have followed these processes- 1.

On the top right in "Application" I have selected my app which I have created.
