Errors:
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 “cache-control” for attribute “http-equiv” on element “meta”.
Bad value “expires” for attribute “http-equiv” on element “meta”.
Bad value “pragma” for attribute “http-equiv” on element “meta”.
Using the “meta” element to specify the document-wide default language is obsolete. Consider specifying the language on the root element instead.

Bad value “” for attribute “src” on element “img”: Must be non-empty.
Duplicate ID “lastitem”.
Named character reference was not terminated by a semicolon. (Or “&” should have been escaped as “&”.)
The “itemprop” attribute was specified, but the element is not a property of any item.
Warnings:
The “form” role is unnecessary for element “form”.
The first occurrence of ID “lastitem” was here.
