Redirect product listing page

[xav2]

i modified the file /includes/modules/product_listing.php

before
$error_categories = true;

i added
zen_redirect(zen_href_link(FILENAME_PAGE_NOT_FOUND));

but it doesn't work, is there any other method? thanks

Do you possibly have a copy of the product_listing.php in your custom template-override directory (/includes/modules/YOUR_TEMPLATE/product_listing.php). If that file is there, it will be used instead of the default one (/includes/modules/product_listing.php).

P.S. You should always make your modifications to a template-override version; otherwise, your changes will stand a big chance of being overwritten when you upgrade.
