The “hspace” attribute on the “img” element is obsolete. Use CSS instead.
An “img” element must have an “alt” attribute, except under certain conditions. For details, consult guidance on providing text alternatives for images.
The “align” attribute on the “div” element is obsolete. Use CSS instead.
Duplicate ID “smf2b”.
Element “noindex” not allowed as child of element “div” in this context. (Suppressing further errors from this subtree.)

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