(Rescan now...)

Errors:

A “meta” element with an “http-equiv” attribute whose value is “X-UA-Compatible” must have a “content” attribute with the value “IE=edge”.

Attribute “value” not allowed on element “meta” at this point.

Element “meta” is missing one or more of the following attributes: “content”, “property”.

“=” in an unquoted attribute value. Probable causes: Attributes running together or a URL query string in an unquoted attribute value.

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.

Element “noindex” not allowed as child of element “div” in this context. (Suppressing further errors from this subtree.)

No “p” element in scope but a “p” end tag seen.

Element “style” not allowed as child of element “div” in this context. (Suppressing further errors from this subtree.)

The “align” attribute on the “p” element is obsolete. Use CSS instead.

Element “div” not allowed as child of element “ul” in this context. (Suppressing further errors from this subtree.)

Bad value “” for attribute “src” on element “iframe”: Must be non-empty.

The “frameborder” attribute on the “iframe” element is obsolete. Use CSS instead.
