Facebook Open Graph not clearing cache

by
  1. Go to http://developers.facebook.com/tools/debug
  2. Enter the URL following by fbrefresh=CAN_BE_ANYTHING

Examples:

  1. http://www.example.com?fbrefresh=CAN_BE_ANYTHING
  2. http://www.example.com?postid=1234&fbrefresh=CAN_BE_ANYTHING
  3. OR visit:
    http://developers.facebook.com/tools/debug/og/object?q=http://www.example.com/?p=3568&fbrefresh=89127348912

I was having the same issue last night, and I got this solution from some website.

Facebook saves your cache thumbnail. It won’t refresh even if you delete the thumnail/image from your server. But Facebook allows you to refresh by using fbrefresh

I hope this helps.
