But Octoshop Product Plus needs it. Is this plugin still works?

Octoshop was removed, I think due to no support and further development from creator. You can use another solution for october ecommerce if you are starting new one. I'd recommend Shopaholic. But if you are stuck with Octoshop pm me and I will try to help
