debug a django web app to fix errpr

I have a webapp that works perfectly locally but when I hosted it on AWS, part of its functionality fails for some reason. There are small continuality issues between web server (uwsgi) and the API server (django taskmgr) for example with sessions and auth tokens Secondly, there is a greenlet issue The webapp makes great use of websockets and greenlets but there is a bug in the code that needs careful debugging. Its only one file which is causing all of this. I have all the files and access to the server. I have another person who is responsible for hosting who tried to help to fix and is familiar with this but he still faced problems attempting to fix. I want this to be done in one day maximum. It actually should take an hour maximum. NO INDIANS!!!!!!!!!!!!!!!!!!!!!!!
