Odd Error Message

Hi,

There are two things you can try:
- instead of trying to delete it, try to unpublish it via the products listing icon. If it's unpublished it's as if it would be deleted.
- you can use a mass action with a filter on its product_id and an action delete the product to delete it.

Hi,

Well, That means that the system has to handle 20*20*20*20 variants for that product. That's 160 000 entries to load for just one product.
So even increasing your server processing won't help. Loading that much data in one PHP process is not possible.
But that also means that the characteristics/variants system is not what you want to use.
It is useful when you want to configure each variant of the product differently from one another( different stock, or different prices, etc), and I doubt that you're trying to configure 160 000 variants differently from the main product.
So what you want to use instead is either options or custom fields of the item table:
www.hikashop.com/support/documentation/i...ct-form.html#options
www.hikashop.com/support/documentation/4...shop-field-form.html
In both cases, you won't get a combination of all the values generated. And thus, instead of loading 160 000 entries, it will only load 20+20+20+20 => 80 entries for the product, and that's no problem.
