title: Facebook custom share url with custom parameters...works in preview but broken on FB
body: <p>I was trying to create a share button that you can see on this page. There are different products and a custom link to share any item on their own. The store has been personalized with the method ... sharer / sharer.php? Etc.</p>
  
  <p>Below is one of many links. The problem appears after you have shared the article on Facebook: the description does not appear, nor will the image and the title! Why?
  Thanks!</p>
