Hello,
Thanks for the report.
In "components/com_hikamarket/view/ordermarket/view.html.php" please replace
if(!empty($pageInfo->filter->filter_payment))
$filters['order_payment_method'] = 'hkorder.order_payment_method = ' . $db->Quote($pageInfo->filter->filter_payment);
By
if(!empty($pageInfo->filter->filter_payment) && $vendor->vendor_id <= 1)
$filters['order_payment_method'] = 'hkorder.order_payment_method = ' . $db->Quote($pageInfo->filter->filter_payment);
if(!empty($pageInfo->filter->filter_payment) && $vendor->vendor_id > 1)
$filters['order_payment_method'] = 'hkorder.order_payment_method = ' . $db->Quote('market-'.$pageInfo->filter->filter_payment);
We will add that patch in our side for the next release.
Regards,
