I am trying to control which images from my website show up as the options for the Facebook thumbnails when my website is shared on Facebook.
I am using the open graph protocol, entering the following code into the Header section of my custom code section in Pagelines:
<meta property="og:image" content="
When I refresh the Facebook cache of my website (at developers.facebook.com/tools/debug), I get this error message:
"The 'og:url' property should be explicitly provided, even if a value can be inferred from other tags."
Not sure where I'm going wrong! Thanks for the help!
