 * Hi, I have the og:type set for Article, since it is a blog post and noticed a
   structured data error in the webmaster tools:
    publisher A value for the publisher
   field is required. It requires to add: itemprop=”publisher” itemscope itemtype
   =”[https://schema.org/Organization&#8221](https://schema.org/Organization&#8221);
   I am not sure where to place this markup? It is added to the home page, but not
   to the blog posts.
 * Another warning is: mainEntityOfPage.
    The mainEntityOfPage field is recommended.
   Please provide a value if available. Any suggestion?
 * Thank you
    Andrea

 * Someone fixed it with the following code:
 * “publisher”: {
    “@type”: “Organization”, “name”: “insert your name”, “logo”: {“
   @type”: “ImageObject”, “url”: “insert your logo url”, “width”: 320, “height”:
   60 }
 * I am just not sure where it should go.
    Thank you Andrea

 * I’m having the same problem. Is it possible to edit the plugin to allow the code
   provided by customfit?
