Hi,
In the file: "components/com_hikashop/views/cateogry/view.html.php" in the function "listing()" replace the code:
$database->setQuery('SELECT count(a.product_id) AS number_of_products,a.category_id FROM '.hikashop_table('product_category').' AS a INNER JOIN '.hikashop_table('product').' AS b ON a.product_id=b.product_id AND b.product_published>0 AND product_parent_id=0 WHERE a.category_id IN ('.implode(',',$ids).') GROUP BY a.category_id');
By:
$database->setQuery('SELECT count(a.product_id) AS number_of_products,a.category_id FROM '.hikashop_table('product_category').' AS a INNER JOIN '.hikashop_table('product').' AS b ON a.product_id=b.product_id AND b.product_published>0 AND b.product_parent_id=0 WHERE a.category_id IN ('.implode(',',$ids).') GROUP BY a.category_id');
It had been already corrected on our end.
