HTML markup errors and warnings
(Rescan now...)
Errors:
Almost standards mode doctype. Expected “<!DOCTYPE html>”.
Attribute “xmlns:fb” not allowed here.
Attribute “xmlns:addthis” not allowed here.
The “profile” attribute on the “head” element is obsolete.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 “https://api.w.org/” for attribute “rel” on element “link”: The string “https://api.w.org/” is not a registered keyword.
Element “script” must not have attribute “charset” unless attribute “src” is also specified.
Element “style” not allowed as child of element “body” in this context. (Suppressing further errors from this subtree.)
Bad value “screen, projection” for attribute “media” on element “link”: Deprecated media type “projection”. For guidance, see the Media Types section in the current Media Queries specification.
Stray end tag “head”.
Start tag “body” seen but an element of the same type was already open.
Cannot recover after last error. Any further errors will be ignored.
Warnings:
Attribute with the local name “xmlns:fb” is not serializable as XML 1.0.
Attribute with the local name “xmlns:addthis” is not serializable as XML 1.0.
