[facebook] Facebook Open Graph not clearing cache

Ooook, finally it helped (I use IP.Board). What I had to do was:

  1. Change url of og:image on my website (General configuration).
  2. Try this method with ?fbrefresh=1154464gd56

Thanks to author for this thread!

EDIT: What is more you need to remember about image requirements. For now (january 2013) it's: - at least 200 px in both directions - maximum ratio 3:1
