404 Page Not Working

Using the custom 404 page styling doesn't seem to have any effect on my site. E.g. https://georgecriminallawyers.com.au/payments returns the standard "No Results Found" page. The child theme footer 404.php is:

<?php get_header();

$divi_powerful_custom_404_styling_settings = get_option( 'divi_powerful_custom_404_styling_settings', 'none' );

?>

<div id="main-content">
<?php
if ($divi_powerful_custom_404_styling_settings != 'none') { ?>
<div class="free-custom-404-page">
<?php
$dp_404_style = do_shortcode('[et_pb_section global_module="' . $divi_powerful_custom_404_styling_settings . '"][/et_pb_section]');
echo $dp_404_style;
?>
</div> <!-- .free-custom-404-page -->
<?php
} else { ?>
<div class="container">
<div id="content-area" class="clearfix">
<div id="left-area">
<article id="post-0" <?php post_class( 'et_pb_post not_found' ); ?>>
<?php get_template_part( 'includes/no-results', '404' ); ?>
</article> <!-- .et_pb_post -->
</div> <!-- #left-area -->

<?php get_sidebar(); ?>

</div> <!-- #content-area -->
</div> <!-- .container -->
<?php
} ?>
</div> <!-- #main-content -->

<?php

get_footer();

 

Yep, I selected each style and none of them worked.
