Start tag “body” seen but an element of the same type was already open.
An opening <body> tag has been found in an incorrect place. Check that it appears only once in the document, right after the closing </head> tag, and that the whole document content is contained within <body> and </body> tags.

A <meta> element without a itemprop or property attributes has been found in an unexpected place.
While the <meta> element is commonly used within the <head> section of the document, it can also be used within the <body> section, for example in the context of defining microdata, as in this example:
<div itemprop="offers" itemscope itemtype="http://schema.org/Offer">
Price: $<span itemprop="price">1.00</span>
<meta itemprop="priceCurrency" content="USD" />
</div>
When used within the <body> section, the <meta> element is required to have a itemprop or property, and a content attribute, and it can’t have a http-equiv or charset attribute.
A common cause for this issue is including a <meta> element that was intended for the <head> section (for example one containing a http-equiv attribute in the <body> , for example:
<meta http-equiv="content-type" content="text/html; charset=UTF-8">
<form>
...

A closing </body> tag has been found, but there are unclosed elements before it. For example this has an unclosed <section> element:
<body>
<section>
</body>
<meta> tags, used for defining metadata about HTML documents, must appear within the <head>...</head> section, but it has been found out of place. Check the document structure to ensure there are no <meta> tags outside the head section.
A common cause of this issue is having a duplicated, out of place <head>...</head> section. Ensure that this section appears in its proper place and is the only container for <meta> tags.
An end tag has been found after the closing </body> tag, which breaks the expected HTML document structure.
Check out the document structure, a basic example follows:
<!DOCTYPE html>
<html lang="">
<head>
<title>Test</title>
</head>
<body>
<p></p>
</body>
