I’m using Google AMP for my press site.
But I had many validation error.
I found on the internet, it’s maybe one plugin which can cause this error, so I had checked all my plugins and finally I discovered that it’s NextGen gallery which break my validation.
I contact the support but no response.

Can I have some alternative Or advice to fix this ?
I fix the problem with this line to add to your functions.php
add_filter( 'run_ngg_resource_manager', '__return_false' );
