(Rescan now...)
Errors:
Bad start tag in “img” in “head”.
Bad value “https://www.facebook.com/tr?id=361782538091894&ev=PageView
&noscript=1” for attribute “src” on element “img”: Tab, new line or carriage return found.
An “img” element must have an “alt” attribute, except under certain conditions. For details, consult guidance on providing text alternatives for images.
Stray end tag “noscript”.
Stray end tag “head”.
Start tag “body” seen but an element of the same type was already open.
Bad value “button” for attribute “type” on element “a”: Subtype missing.
Element “style” not allowed as child of element “body” in this context. (Suppressing further errors from this subtree.)
The “frameborder” attribute on the “iframe” element is obsolete. Use CSS instead.
Stray end tag “div”.
The “aria-controls” attribute must point to an element in the same document.
Warnings:
Empty heading.
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).
