Attribute “debug” not allowed on element “script” at this point.

Warnings:
The “type” attribute is unnecessary for JavaScript resources.

The “navigation” role is unnecessary for element “nav”.

The first occurrence of ID “menu-main-menu” was here.
The “border” attribute is obsolete. Consider specifying “img { border: 0; }” in CSS instead.
Consider using the “h1” element as a top-level heading only (all “h1” elements are treated as top-level headings by many screen readers and other tools).
