HTML markup errors and warnings
(Rescan now...)
Errors:
Element “base” not allowed as child of element “head” in this context. (Suppressing further errors from this subtree.)
An “img” element must have an “alt” attribute, except under certain conditions. For details, consult guidance on providing text alternatives for images.
Bad value “” for attribute “action” on element “form”: Must be non-empty.
The “frameborder” attribute on the “iframe” element is obsolete. Use CSS instead.
Attribute “monitor-desc” not allowed on element “div” at this point.
Bad value “###” for attribute “href” on element “a”: Illegal character in fragment: “#” is not allowed.
“=” in an unquoted attribute value. Probable causes: Attributes running together or a URL query string in an unquoted attribute value.
