My website, which was working before, suddenly started breaking with the error
ImproperlyConfigured at / The included urlconf resume.urls doesn\'t h
IN my case I got this error during deployment. Apache kept giving me the "AH01630: client denied by server configuration" error. This indicated that was wrong with apache configuration. To help troubleshoot I had turned on Debug=True in settings.py when I saw this error.
In the end I had to add a new directive to the static files configuration inside apache config. When the static files were not accessible and Debug in django settings was set to true this error was getting triggered somehow.
