The “itemprop” attribute was specified, but the element is not a property of any item.
An itemprop attribute has been found in the document, but it cannot be associated to any item. Most probable cause is the lack of an itemscope attribute defining an item.

<div itemscope>
<p>My name is <span itemprop="name">Liza</span> and I'm <span itemprop="age">48</span> years old.</p>

<meta http-equiv="content-type" content="text/html; charset=UTF-8">
