 * In the backend, the “selz” button in the toolbar is “invisible”, the icon is 
   missing. Thats fine..
 * In the front end, “buy now” button don’t show. JS error
    Firefox : TypeError:

   length’ of undefined

 * Ok it works. I was copying the wrong link. It need to be the “short link” of 
   your video.
