Hi Steven,

I installed this add-on and works well. (zen cart v1.3.7, hideCategories v1.00) Thanks!

Just minor thing that in

admin\includes\modules\category_product_listing.php

there're

Code:
<?php echo '<a href="' . zen_href_link(FILENAME_STOCK_MANAGER, 'cPath=' . $cPath . '&product_type=' . $products->fields['products_type'] . '&pID=' . $products->fields['products_id'] .'&action=stock_manager' ) . '">' . zen_image(DIR_WS_IMAGES . 'icon_stock_manager.gif', ICON_STOCK_MANAGER) . '</a>'; ?>
        <?php echo '<a href="' . zen_href_link(FILENAME_IMAGE_HANDLER, 'products_filter=' . $products->fields['products_id'] . '&current_category_id=' . $current_category_id) . '">' . zen_image(DIR_WS_IMAGES . 'icon_image_handler.gif', ICON_IMAGE_HANDLER) . '</a>'; ?>

I don't use stock manager and image handler so I guess it's safe to remove these lines.

Cheers
