I'm trying to embed a Pinterest link, like explained here.
I've added this Pinterest link to a blog:
<a href="https://www.pinterest.com/pin/139330182194785581/" data-pin-do="embedPin"></a>
I've also added script <script type="text/javascript" async src="//assets.pinterest.com/js/pinit.js"></script>
before my </body>
tag.
But the Pinterest image does not show. See a live example here.
From the errors in the Chrome console I don't learn why.
What can I do?
