I have created a custom storage backend, the file is called storages.py and is placed in an app called core:
storages.py
core
from django.conf impor
Typo error. Change:
DEFAULT_FILE_STORAGE = 'storages.backends.s3boto.S3BotoStorage'
TO:
DEFAULT_FILE_STORAGE = 'storages.backends.s3boto.S3Boto3Storage'
