404 Page Not Working

Yes, my 404.php in the child theme was set to a filesize of 0 bytes after my site was hacked. I made a copy of the 404 file in the Genesis folder and modified it.

That said, I want to customize the 404 page so that I can choose what contents to display. Some things like authors doesn't make sense to display. The main code calls genesis_sitemap so I'm thinking that I can modify that function in the child theme. I put some quick code in place to display just the page names/links. I seem to remember there's an easy way to customize the 404 page within the console but I haven't been able to find it.

remove_action( 'genesis_loop', 'genesis_do_loop' );

add_action( 'genesis_loop', 'genesis_404' );
/**
* This function outputs a 404 "Not Found" error message
*
* @since 1.6
*/
function genesis_404() {

echo genesis_html5() ? '<article class="entry">' : '<div class="post hentry">';

printf( '<h1 class="entry-title">%s</h1>', apply_filters( 'genesis_404_entry_title', __( 'Not found, error 404', 'genesis' ) ) );
echo '<div class="entry-content">';
if ( genesis_html5() ) :
echo apply_filters( 'genesis_404_entry_content', '<p>' . sprintf( __( 'The page you are looking for no longer exists. Perhaps you can return back to the site\'s homepage and see if you can find what you are looking for. Or, you can try finding it by using the search form below.', 'genesis' ), trailingslashit( home_url() ) ) . '</p>' );
get_search_form();
else :
?>
<p><?php printf( __( 'The page you are looking for no longer exists. Perhaps you can return back to the site\'s homepage and see if you can find what you are looking for. Or, you can try finding it with the information below.', 'genesis' ), trailingslashit( home_url() ) ); ?></p>
<?php
endif;
/** MODIFIED CODE */ wp_list_pages( 'title_li=' );
echo '</div>';
}

genesis();

/** ORIGINAL CODE - this is the code I replace with the above modified code */
if ( ! genesis_html5() ) {
genesis_sitemap( 'h4' );
} elseif ( genesis_a11y( '404-page' ) ) {
echo '<h2>' . __( 'Sitemap', 'genesis' ) . '</h2>';
genesis_sitemap( 'h3' );
}
echo '</div>';
echo genesis_html5() ? '</article>' : '</div>';
