Facebook is picking up the wrong image from my Magento web site when shared. I have added the following line to my head.phtml
<meta property="og:image" content="https://www.sturdykids.co.uk/skin/frontend/default/megashop-blue/images/logo.gif" />
It is definately in the right place when I view source of web site but the facebook debugger is still saying there is no og:image property.
What can I do to fix this?
