(Rescan now...)
Errors:
Element “script” must not have attribute “charset” unless attribute “src” is also specified.
Bad value “https://api.w.org/” for attribute “rel” on element “link”: The string “https://api.w.org/” is not a registered keyword.
Quote “"” in attribute name. Probable cause: Matching quote missing somewhere earlier.
Attribute “boosteria""” not allowed on element “img” at this point.
End tag “br”.
Element “p” not allowed as child of element “h3” in this context. (Suppressing further errors from this subtree.)
Bad character “3” after “<”. Probable cause: Unescaped “<”. Try escaping it as “<”.

Duplicate ID “this_is_blue”.
Duplicate ID “fb-root”.
Warnings:
