I installed the extension and can not export orders. I have joomla 3.5.1 and Virtuemart 3.0.16 and this is the error in the console when I try to export the last order placed:
POST www.mysite.com/administrator/index.php?o...m&view=orders&prev=1 500 (Subquery returns more than 1 row SQL=SELECT virtuemart_order_id as order_id,`order_number`,`created_on` as order_date,order_subtotal as order_subtotal,`coupon_code` as coupon,order_discount as discount, (SELECT `order_status_name` FROM `#__virtuemart_orderstates` WHERE `order_status_code` = order_status) as order_status,order_total,order_billTaxAmount as total_tax,(SELECT `payment_element` FROM `#__virtuemart_paymentmethods` = virtuemart_paymentmethod_id) as payment_method,(SELECT `shipment_element` FROM `#__virtuemart_shipmentmethods` WHERE `virtuemart_shipmentmethod_id` = virtuemart_shipmentmethod_id) as ship_method,order_pass as secret_key,(SELECT `currency_code_3` FROM `#__virtuemart_currencies` WHERE `virtuemart_currency_id` = order_currency) as currency_code_3,(SELECT `currency_symbol` FROM `#__virtuemart_currencies` WHERE `virtuemart_currency_id` = order_currency) as currency_symbol FROM `#__virtuemart_orders` WHERE `virtuemart_order_id` = '1075')
