(Rescan now...)
Errors:
Bad value “” for attribute “media” on element “link”: Media query ended prematurely.

No “li” element in scope but a “li” end tag seen.
End tag “div” seen, but there were open elements.
Unclosed element “ul”.
Duplicate ID “menu-main-menu-1”.
Unclosed element “span”.
An “img” element must have an “alt” attribute, except under certain conditions. For details, consult guidance on providing text alternatives for images.
Element “style” not allowed as child of element “div” in this context. (Suppressing further errors from this subtree.)
Warnings:
The “banner” role is unnecessary for element “header”.
The “navigation” role is unnecessary for element “nav”.
The first occurrence of ID “menu-main-menu-1” was here.
Section lacks heading. Consider using “h2”-“h6” elements to add identifying headings to all sections.
Consider using the “h1” element as a top-level heading only (all “h1” elements are treated as top-level headings by many screen readers and other tools).
Empty heading.
The “name” attribute is obsolete. Consider putting an “id” attribute on the nearest container instead.
The “contentinfo” role is unnecessary for element “footer”.
