title: Change og:url in WordPress SSL site to point to http
body: <p>I have moved to SSL recently but lost all FB likes. I have seen other answers here, I.e. <a href="https://stackoverflow.com/questions/29532848/lost-all-likes-while-moving-to-https">Lost all Likes while moving to HTTPS</a> but don't know how to apply it. For example, in Simple Facebook Plugin I can see the code:</p>
  
  <pre><code>$fbmeta['og:url'] = esc_url($permalink);
  </code></pre>
  
  <p>How do I change that so that it gets the http version?</p>
