Autopost is not working I want to autopost the contents in facebook.I installed Drupal for Facebook module and created Apps in facebook.

In this,the user can connect facebook.But the content doesn't get autopost.
I got an error like this 

"Something went wrong while posting update to your facebook wall. The error has been captured by watchdog".

How to clear this error.
Your error says your application has been deleted. Go to https://developers.facebook.com and check your application under the "Apps" tab. If the app exists, check that your oauth details (on the drupal site) match. If the app doesn't exist, create an app (also under the "Apps" tab) and validate against that in your Drupal site's oauth settings.
