Attribute “xmlns:fb” not allowed here.
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 “Content-Script-Type” for attribute “http-equiv” on element “meta”.
Bad value “Content-Style-Type” for attribute “http-equiv” on element “meta”.
Bad value “true” for attribute “async” on element “script”.
Element “style” not allowed as child of element “body” in this context. (Suppressing further errors from this subtree.)
