Developer needed who is a Celery/Redis expert in python.

I have a Django website where I am using Redis as a broker and celery as queue management system. My website is based in python Django framework. In my architecture, I have a main machine which uses redis as a broker to sends tasks to a worker machine which uses celery worker to get tasks into [login to view URL] and execute them. The problem I am having is that Celery gives out an error because it is using some old cached version of [login to view URL](which persumably had errors). I have restarted worker and server(nginx) but it still gives out the same error. The exact description of the problem is here: [login to view URL] I have tried this solution as well but nothing seems to be working. I want the developer to fix this issue and get my system up and running again. The developer should be available to start work immediately and finish it asap.
