I can not create a store on facebook with the widget, it gives me the following error:
This page does not have permission to install the custom tab.
I created an app and inserted the url and it works, but I want to use the add of cscart with the widget, I read that with the multivendor you do not have to buy the license, possible?
API Error Code: 191 API Error Description: The specified URL is not owned by the application Error Message: redirect_uri is not owned by the application.
