There was an import in base.models file, from django.contrib.auth.backends import ModelBackend which caused this error even when i removed custom AUTHENTICATION_BACKENDS.after i removed this import, everything works fine although i moved backend class from base.models to backend file in the base app (i think its not necessary, i just did it for more readable codes)
