Element “div” not allowed as child of element “ul” in this context. (Suppressing further errors from this subtree.)
The “align” attribute on the “div” element is obsolete. Use CSS instead.
End tag “br”.
The “frameborder” attribute on the “iframe” element is obsolete. Use CSS instead.
Start tag “a” seen but an element of the same type was already open.
End tag “div” seen, but there were open elements.
