The file to amend is the the customer/products.php file
Line 61 is:
Code:
$search_query = "($sql_tbl[products].categoryid='$cat' or $sql_tbl[products].categoryid1='$cat' or $sql_tbl[products].categoryid2='$cat' or $sql_tbl[products].categoryid3='$cat') and $sql_tbl[products].forsale='Y' group by $sql_tbl[products].productid order by $sql_tbl[products].orderby ".($config["General"]["product_order_reversed"]=="Y"?"desc":"asc")." limit $first_page, ".$config["General"]["products_per_page"];
Change this to:
Code:
$search_query = "($sql_tbl[products].categoryid='$cat' or $sql_tbl[products].categoryid1='$cat' or $sql_tbl[products].categoryid2='$cat' or $sql_tbl[products].categoryid3='$cat') and $sql_tbl[products].forsale='Y' group by $sql_tbl[products].productid order by $sql_tbl[pricing].product ".($config["General"]["product_order_reversed"]=="Y"?"desc":"asc")." limit $first_page, ".$config["General"]["products_per_page"];
