(Rescan now...)
Errors:
Saw “<!--” within a comment. Probable cause: Nested comment (not allowed).
A “meta” element with an “http-equiv” attribute whose value is “X-UA-Compatible” must have a “content” attribute with the value “IE=edge”.
Bad value “https://api.w.org/” for attribute “rel” on element “link”: The string “https://api.w.org/” is not a registered keyword.
Bad value “https://theeventscalendar.com/” for attribute “rel” on element “link”: The string “https://theeventscalendar.com/” is not a registered keyword.
Start tag “a” seen but an element of the same type was already open.
Stray end tag “a”.
Element “div” not allowed as child of element “ul” in this context. (Suppressing further errors from this subtree.)
Bad value “100%” for attribute “width” on element “iframe”: Expected a digit but saw “%” instead.
The “frameborder” attribute on the “iframe” element is obsolete. Use CSS instead.
No space between attributes.
The “itemprop” attribute was specified, but the element is not a property of any item.
Warnings:
The document is not mappable to XML 1.0 due to two consecutive hyphens in a comment.
