(Rescan now...)
Errors:

Bad value “language” for attribute “http-equiv” on element “meta”.
Bad value “”og:url”” for attribute “property” on element “meta”: The string “”og:url”” is not an absolute URL.
An “img” element must have an “alt” attribute, except under certain conditions. For details, consult guidance on providing text alternatives for images.
Bad value “” for attribute “name” on element “button”: Must not be empty.
Element “div” not allowed as child of element “span” in this context. (Suppressing further errors from this subtree.)
No “p” element in scope but a “p” end tag seen.
Element “li” not allowed as child of element “div” in this context. (Suppressing further errors from this subtree.)
Attribute “u” not allowed on element “span” at this point.
Start tag “a” seen but an element of the same type was already open.
