Please copy/paste the console output from your runserver console - that’ll show any errors and HTTP response codes generated from the request. It would probably also be helpful to see the template (index.html) to verify that the right references are present, along with verification that the referenced js/css files are in the proper locations.
(Note: When posting these references, please enclose them between lines consisting of three backtick (`) characters. In other words, you would have one line with only ```, followed by your code, followed by another line with only ```. Be sure you use the backtick character (`) and not the apostrophe (’). )
