Attribute “pagespeed_no_defer” not allowed on element “script” at this point.
Attribute “pagespeed_url_hash” not allowed on element “img” at this point.
Element “ul” not allowed as child of element “ul” in this context. (Suppressing further errors from this subtree.)
Element “form” not allowed as child of element “ul” in this context. (Suppressing further errors from this subtree.)
End tag “ul” seen, but there were open elements.
Unclosed element “form”.
Stray end tag “form”.
Saw “<!--” within a comment. Probable cause: Nested comment (not allowed).

The document is not mappable to XML 1.0 due to two consecutive hyphens in a comment.
The first occurrence of ID “o_switcher” was here.
This document appears to be written in English. Consider adding “lang="en"” (or variant) to the “html” start tag.
