Most popular products on 404 page

Is there any simple way to put in public_html/index.php in error 404 section? There is some wasted space ;)

You would have to rewrite pages/error_document.inc.php to do so.

Yyy? Errors 404 are handling by index.php

EDIT: So simple ;) in /public_html/index.php put this:

include vmod::check(FS_DIR_HTTP_ROOT . WS_DIR_BOXES . 'box_most_popular_products.inc.php');

after this:

echo 'Could not find a matching reference for '. parse_url($_SERVER['REQUEST_URI'], PHP_URL_PATH) .'.';

You are starting to know the platform better than us. Lol. My bad. :)
