i changed plugin into another my subdoamin but it not woking

At first I bought this plguin for my child’s domain name brands.hacano.com but then I switched to bacodo.hacano.com and bacodo1.hacano.com. But when adding the product there was a complete error, what should I do to fix it? I bought your product on https://themeforest.net/ because I wanted to import faster so I divided the domain name so that when I click import list quickly, and each child website will import 2 to 3 main aliexpress catalogs, because our main websites use magento2, so there is no faster method, we can only split it into small parts.
