Removing a post author

There are a few methods of removing the author. The website has a section on modifying the author information via a reader mode template override.

Another option is to add the below to your active themes functions.php file:

add_filter( 'amp_post_article_header_meta', 'xyz_amp_remove_author_meta' );
function xyz_amp_remove_author_meta( $meta_parts ) {
	foreach ( array_keys( $meta_parts, 'meta-author', true ) as $key ) {
		unset( $meta_parts[ $key ] );
	}
	return $meta_parts;
}

You could also use a CSS approach, although if you’re using reader mode it would also need to be added to your functions.php file (reader mode does not use your active themes stylesheets).

add_action( 'amp_post_template_css', function() {
        ?>
        [amp] .amp-wp-meta{display:none}
        <?php
} );
