&noscript=1” for attribute “src” on element “img”: Tab, new line or carriage return found.
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 “noscript”.
Stray end tag “head”.
Start tag “body” seen but an element of the same type was already open.
Element “div” not allowed as child of element “ul” in this context. (Suppressing further errors from this subtree.)

Warnings:
The “type” attribute is unnecessary for JavaScript resources.
The “name” attribute is obsolete. Consider putting an “id” attribute on the nearest container instead.
