There isnt an option to disable the WooComerce app in the customizer. The only option is to buy now.
I can install the plugin and it gets the cart to show up and the error message to go away but I dont want the cart as I dont want to do an Ecommerce site. As soon as the plugin is disabled the error comes back.
If you want we can review the issue, make a user for us assign administrator role and send us the username and password along with the URL at support@vwthemes.com.
