Ho to remove URL / Website field from comments section

Replies: 1

Hello there, I am trying to remove the URL/Website field from the comments section on this page by following this
https://wordpress.org/support/topic/unable-to-disable-website-field-in-comments/

Added the following to the functions.php

function remove_comment_fields( $fields ) {
	unset( $fields['url'] );
	return $fields;
}
add_filter( 'comment_form_default_fields', 'remove_comment_fields', 60 );

It did not work. Can anyone shed some light on what I am missing? Thanks in advance.
