The page has no main content area marked
landmark-one-main
Nothing on the page identifies where the main content starts, so assistive software cannot offer a shortcut past the header and menu.
Who this affects
Screen reader users, who otherwise have to listen through the entire menu on every single page.
Fix it in WordPress
Add <main id="content"> around the loop in the theme's page.php, single.php, index.php and archive.php. Most modern themes already do this; older and heavily customised ones often do not.
What the fix is, technically
Wrap the primary content in a main element, or an element with role="main". Use exactly one per page.
