The plugin is configured to work on a Themosis framework like environment only.
It extends WooCommerce functionalities.
You can manager custom order statuses within the back-office and enable / disable product types from the configuration file of your application.
To enable or disable product type, go to your config/app.php file and set the following value:
return [ [...] 'woocommerce' => [ 'product_types' => [ 'virtual' => [ 'disabled' => true, ], 'downloadable' => [ 'disabled' => true, ], 'external' => [ 'disabled' => true, ], ], ], ];
Read the documentation on the Themosis framework website and start developing your own plugin.
