HTML markup errors and warnings
(Rescan now...)
Errors:
Almost standards mode doctype. Expected “<!DOCTYPE html>”.
Attribute “xmlns:fb” not allowed here.
Using the “meta” element to specify the document-wide default language is obsolete. Consider specifying the language on the root element instead.
Bad value “cache-control” for attribute “http-equiv” on element “meta”.
Bad value “”fb:page_id”” for attribute “property” on element “meta”: The string “”fb:page_id”” is not an absolute URL.
Element “fb:like” not allowed as child of element “div” in this context. (Suppressing further errors from this subtree.)
Element “div” not allowed as child of element “ul” in this context. (Suppressing further errors from this subtree.)
The “center” element is obsolete. Use CSS instead.
Stray end tag “a”.
Stray end tag “h3”.
Duplicate ID “fb-root”.
Warnings:
Attribute with the local name “xmlns:fb” is not serializable as XML 1.0.
Element name “fb:like” cannot be represented as XML 1.0.
The first occurrence of ID “fb-root” was here.
