Element “meta” is missing one or more of the following attributes: “itemprop”, “property”.

A “link” element must not appear as a descendant of a “body” element unless the “link” element has an “itemprop” attribute or has a “rel” attribute whose value contains “dns-prefetch”, “modulepreload”, “pingback”, “preconnect”, “prefetch”, “preload”, “prerender”, or “stylesheet”.

Stray end tag “head”.

Start tag “body” seen but an element of the same type was already open.
