[FIXED] ImportError: cannot import name 'Page'

Issue

I have written a game in an Otree Project, but every time i want to clean my database or start the server, this message appears. It only happens with my game, but not when an example game is using that command.

Solution

Look in your app for the folder _builtin. There should be a file __init__.py that has the same contents as every other app's _builtin/__init__.py. If not, copy it from the other app.
