django - 'Python manage.py runserver' "ValueError: Unable to configure handler 'mail_admins'".:

Question

I'm working on a Django project.

When starting the server I get "ValueError: Unable to configure handler 'mail_admins'". I'm in the correct directory, with virtual environment started.

I can't make migrations, same error apears.

Everything was working fine was able to start the server on this method in the past with no problem, until today.

Thanks in advance!

Answer 1

It seems that the error is arisen from the LOGGING in the settings of the project. Take a look in the LOGGING['handlers'].
