You can edit the file administrator/components/com_hikashop/classes/cart.php and change the code:
Code:
foreach($variant->characteristics as $k => $val){
$i = 0;
$ordering = @$element->characteristics[$val->characteristic_parent_id]->ordering;
while(isset($chars[$ordering])&& $i < 30){
$i++;
$ordering++;
}
$chars[$ordering] = $val;
}
to:
Code:
if(!empty($variant->characteristics)){
foreach($variant->characteristics as $k => $val){
$i = 0;
$ordering = @$element->characteristics[$val->characteristic_parent_id]->ordering;
while(isset($chars[$ordering])&& $i < 30){
$i++;
$ordering++;
}
$chars[$ordering] = $val;
}
}
and that will remove these warning messages.
