[ERROR/MainProcess] Received unregistered task of type 'djcelery_email_send_multiple'.

I'm trying to use the app to send emails but I'm always facing an error.

These are the packages in my environment:

Django==1.8.3
amqp==1.4.6
anyjson==0.3.3
billiard==3.3.0.20
celery==3.1.18
django-appconf==1.0.1
django-celery==3.1.16
django-celery-email==1.1.2
django-jfu==2.0.9
kombu==3.0.26
psycopg2==2.6.1
pytz==2015.4
six==1.9.0
wsgiref==0.1.2

settings.py

**
INSTALLED_APPS = (
    ***
    'djcelery',
    'kombu.transport.django',
    'djcelery_email',
    ***
)
**

CELERY_RESULT_BACKEND = 'djcelery.backends.database:DatabaseBackend'

CELERY_IMPORTS = ["djcelery_email.tasks"]

celery.py

from __future__ import absolute_import
from celery import Celery

app = Celery('job_costing',
             broker='django://')

if __name__ == '__main__':
    app.start()

init.py

from __future__ import absolute_import

# This will make sure the app is always imported when
# Django starts so that shared_task will use this app.
from .celery import app as celery_app

I added autodiscover_tasks to celery.py and it's working.

celery.py

from __future__ import absolute_import
from celery import Celery
from django.conf import settings

app = Celery('job_costing',
             broker=settings.CELERY_BROKER_URL)
app.config_from_object('django.conf:settings')
app.autodiscover_tasks(settings.INSTALLED_APPS)

if __name__ == '__main__':
    app.start()
