Facebook Like button Error

I have the plugin Simple Facebook Like Widget by AJ Batac and my like button doesnt work. Every time I click Like it says error and if you click error this message appears:

“Your page’s type requires that a meta tag of the form <meta property=”og:image” …> be present.”

I have no idea what that means or how to fix it.

Any help would be greatly appreciated.
