HTML markup errors and warnings
(Rescan now...)
Errors:
Saw “<?”. Probable cause: Attempt to use an XML processing instruction in HTML. (XML processing instructions are not supported in HTML.)
Almost standards mode 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).
When the attribute “xml:lang” in no namespace is specified, the element must also have the attribute “lang” present with the same value.
Internal encoding declaration “iso-8859-1” disagrees with the actual encoding of the document (“utf-8”).
Bad value “text/html; charset=iso-8859-1;” for attribute “content” on element “meta”: The legacy encoding contained “;”, which is not a valid character in an encoding name.
Using the “meta” element to specify the document-wide default language is obsolete. Consider specifying the language on the root element instead.
Element “g:plusone” not allowed as child of element “li” in this context. (Suppressing further errors from this subtree.)
Warnings:
Attribute “xmlns” is not serializable as XML 1.0.
Element name “g:plusone” cannot be represented as XML 1.0.
This document appears to be written in English. Consider adding “lang="en"” (or variant) to the “html” start tag.
