Element “head” is missing a required instance of child element “title”.
The <head> section of an HTML document contains metadata about the document, and as a minimum it must include a <title> tag defining the document title.
Common causes for this issue are forgetting to define the <title>, or duplicated <head> sections where one of them does not include the title.
Here’s an example of a minimal HTML document including the title:
<!DOCTYPE html>
<html>
<head>
<title>Don't panic! This is the title</title>
</head>
<body>
<p></p>
</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.
A <head> start tag has been found in an unexpected place in the document structure. Check that the <head> section appears before the <body> section, and that is not duplicated.
