I just checked the code and a modification has already been made.
Can you check in "plugins\hikashop\massaction_product\massaction_product.php" if the function is:
function onProcessProductMassActiondeleteElements(&$elements,&$action,$k, $start = 0){
$ids = array();
$i = 0;
$productClass = hikashop_get('class.product');
foreach($elements as $element){
$nb = $i - $start;
if($nb >= 0 && $nb < 500){
$ids[] = $element->product_id;
$i++;
}elseif($nb >= 500){
$result = $productClass->delete($ids);
$start = $start + 500;
$this->onProcessProductMassActiondeleteElements($elements,$action,$k, $start);
}
}
}
If it's not, thansk to replace it.
