title: Facebook sharer showing (almost) always the wrong author
body: <p>I can't understand why Facebook sharer keeps showing the wrong article's author when sharing articles of my website. (Of course I always use Facebook Debugger before sharing).</p>
  
  <p>Take this <a href="http://wordsinthebucket.com/u-turn-indonesia-virginity-tests" rel="noreferrer">article</a> as an example: although it is clearly written by Francesca Aloisio, it keeps showing (when shared) "by Virginia Vigliar". </p>
  
  <p>Facebook Debugger reports:</p>
  
  <pre><code>&lt;meta property="article:publisher" content="https://www.facebook.com/wordsinthebucket" /&gt;
  &lt;meta property="article:author" content="https://www.facebook.com/francesca.aloisio.397" /&gt;
  </code></pre>
  
  <p>I just can't figure out why.</p>
  
  <p>N.B. I use Wordpress SEO by Yoast.</p>
