We have setup a Development server, and copied everything from the production. But after installing Celery and Rabbitmq The celery does not work as intended. We need someone to login to our development server, and make the cellery to work ( by either reinstalling it and its dependency or re-configuring it correctly on a Centos OS ). The python and PHP scripts are all 100% ready as they were working on production correctly. After shifting them to this new server, due to some server environment or difference in version it seems not working.
