HTML markup errors and warnings
(Rescan now...)
Errors:
Saw “<?”. Probable cause: Attempt to use an XML processing instruction in HTML. (XML processing instructions are not supported in HTML.)
Almost standards mode doctype. Expected “<!DOCTYPE html>”.
Attribute “xmlns:fb” not allowed here.
Bad value “async” for attribute “defer” on element “script”.
A “meta” element with an “http-equiv” attribute whose value is “X-UA-Compatible” must have a “content” attribute with the value “IE=edge”.
Element “object” is missing one or more of the following attributes: “data”, “type”.
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 “head”.
Start tag “body” seen but an element of the same type was already open.
Cannot recover after last error. Any further errors will be ignored.
Warnings:
Attribute with the local name “xmlns:fb” is not serializable as XML 1.0.
The “language” attribute on the “script” element is obsolete. You can safely omit it.
