The whole page is hidden from screen readers
aria-hidden-body
The entire page is marked as hidden from assistive software, making it completely unusable.
Who this affects
Every screen reader user. This is as severe as it gets.
Fix it in WordPress
Almost always a modal or popup plugin that failed to clean up after closing. Disable plugins one by one to find it.
What the fix is, technically
Remove aria-hidden from the body element.
