Hi,
I think that Mohamed didn't have the right sample data for his test ; I reproduced the issue in my test website.
In the file "administrator/components/com_hikashop/classes/widget.php" please replace
if($csv && ($widget->widget_params->content=='orders' || $widget->widget_params->content=='sales')){
$leftjoin[]=' LEFT JOIN #__hikashop_address AS address1 ON a.order_billing_address_id=address1.address_id';
$select.=',address1.*';
}
By
if($widget->widget_params->content=='orders'){
$limit = ' GROUP BY a.order_id '.$limit;
}
if($csv && ($widget->widget_params->content=='orders' || $widget->widget_params->content=='sales')){
$leftjoin[]=' LEFT JOIN #__hikashop_address AS address1 ON a.order_billing_address_id=address1.address_id';
$select.=',address1.*';
}
It should fix your issue.
Regards,
