WSGI.py django.core.exceptions.ImproperlyConfigured: WSGI application

Обновлял WhiteNoise и вносил изменения в wsgi.py Затем узнал, что в новой версии уже не нужно редактировать WSGI. Вернул обратно, но теперь выдает ошибку django.core.exceptions.ImproperlyConfigured: WSGI application 'mysite.wsgi.application' could not be loaded; Error importing module.

Не могу найти ошибку. Вот код. Подскажите, пожалуйста!
