Errors:
Saw “<?”. Probable cause: Attempt to use an XML processing instruction in HTML. (XML processing instructions are not supported in HTML.)
Legacy doctype. Expected “<!DOCTYPE html>”.
Bad value “https://www.w3.org/1999/xhtml” for the attribute “xmlns” (only “http://www.w3.org/1999/xhtml” permitted here).
Attribute “xmlns:og” not allowed here.
Attribute “xmlns:geo” not allowed here.
Attribute “xmlns:foaf” not allowed here.
Attribute “xmlns:ctag” not allowed here.
Attribute “xmlns:dbp” not allowed here.
When the attribute “xml:lang” in no namespace is specified, the element must also have the attribute “lang” present with the same value.
The “profile” attribute on the “head” element is obsolete. To declare which “meta” terms are used in the document, instead register the names as meta extensions. To trigger specific UA behaviors, use a “link” element instead.
Bad value “X-Xss-Protection” for attribute “http-equiv” on element “meta”.
A “meta” element with an “http-equiv” attribute whose value is “X-UA-Compatible” must have a “content” attribute with the value “IE=edge”.
Bad value “application/xhtml+xml; charset=UTF-8” for attribute “content” on element “meta”: The legacy encoding declaration did not start with “text/html;”.
Self-closing syntax (“/>”) used on a non-void HTML element. Ignoring the slash and treating as a start tag.
End tag “div” seen, but there were open elements.
Unclosed element “span”.
The “acronym” element is obsolete. Use the “abbr” element instead.
Bad value “popup standard 800 600 noicon nofollow” for attribute “rel” on element “a”: The string “popup” is not a registered keyword.
