I have installed the plugin on http://keeping-chickens.me.uk
Unfortunately when using the Facebook debug page for the URLs on this site, it is returning:
The image referenced by the url of og:image tag could not be downloaded.
Strangely underneath this error, in the Open Graph data it does list out the images that are picked up by the plugin, as well as the 'default' logo, in other words:
Meta Tag <meta property="og:image" content="http://keeping-chickens.me.uk/wp-content/uploads/2013/03/keeping-chickens-logo-500x575.jpg" />
Can anyone help? This plugin looks good and I'd like to stick with it so would be thrilled to get this working :-)
