For the plugin to work, WordPress needs to be installed at the domain or subdomain level, not at the page level. For example, If you are developing a store for a client and you’re creating a mockup on
www.example.com/dev/. Our server will try to connect to the WooCommerce API at the subdomain level
www.example.com but the store is on
www.example.com/dev/. As an alternative, you can install the development store on the
dev.example.com subdomain, with this our applications will connect to the store as expected.
