You might need to edit it to add Boxes back in...

<?php
/*

//This removes the Check box for save email address
add_filter( 'comment_form_default_fields', 'tu_comment_form_hide_cookies_consent' );
function tu_comment_form_hide_cookies_consent( $fields ) {
unset( $fields['cookies'] );
return $fields;
}
//This remove fields Website (url) - Name (author) - email
//Remove eg $fields['url'], to add the Website field back in
function remove_website_name_email_field( $fields ){
if(isset($fields['url'],$fields['author'],$fields['email']))
unset($fields['url'],$fields['author'],$fields['email']);
return $fields;
}

add_filter( 'comment_form_default_fields', 'remove_website_name_email_field' );
