Thanks for the report, please edit the file "plugins/hikashop/massaction_product/massaction_product.php" and replace the function "onProcessProductMassFilterproductColumn" by:
Code:
function onProcessProductMassFilterproductColumn(&$elements,&$query,$filter,$num){
if(empty($filter['type']) || $filter['type']=='all') return;
if(!isset($this->massaction))$this->massaction = hikashop_get('class.massaction');
if(count($elements)){
foreach($elements as $k => $element){
if(isset($element->$filter['type'])){
$in = $this->massaction->checkInElement($element, $filter);
if(!$in) unset($elements[$k]);
}
}
}else{
$db = JFactory::getDBO();
if($filter['value'] == 0 || !empty($filter['value']) || (empty($filter['value']) && in_array($filter['operator'],array('IS NULL','IS NOT NULL')))){
$query->where[] = $this->massaction->getRequest($filter,'hk_product');
}
}
}
