Only blank screen

[rigolef]

Code is running fine without errrors, but I only see a blank page on http://127.0.0.1:5000.

In order to make sure that the system is running you need to make sure that you follow the creation of the folders and the files, once you have them exactly as shown you need to run the app from the main.py file

It should show you that the app is running.

Please attach a copy of your code and screenshots of the output you are getting.
