I therefore went back to the app, exported my data using the Export button in the Options screen. When I navigate back to the admin web and login, I get the same error.
I'm sort of believing that there is no admin website for Basketball. However the fact that I can create an ID, change my password and export my database from the app makes me second guess that conclusion.B You have not exported a database to the server!
Can someone point me in the right direction?
