I have deleted the image formerly used as a blog icon from my site (including media gallery). I have uploaded a new one. When I now post a link from my blog into a Facebook status update the old blog icon image appears in the link (like in the third post in page below).
It also continues to appear in old shares on Facebook, the new image has not linked in to update these. I have tried clearing the cache. This can be seen in the third post on this page: https://www.facebook.com/phoenixhandfasting
How can I stop both of these? Thanks.
The blog I need help with is phoenixhandfastingdublin.wordpress.com.
