This is based on a new installation of the software.
The example query provided in SQL-Injection-Interpolation.md no longer works as the database no longer allows more than one SQL statement to be executed (an error is thrown).
An injection payload that does work, however, is:
http://127.0.0.1:8000/admin/1/analytics/?ip=184.166.51.156&password from app_user--
This injects after that first SELECT and then comments out the remainder of the statement.
