How to debug
* Open a *.py file and put a print statement there. OR use python debuggers like pdb and pudb.
Example:
#vim /edx/app/edxapp/edx-platform/lms/envs/aws.py

* Then run the server in debug mode
#sudo -u www-data /edx/bin/python.edxapp ./manage.py lms runserver 0.0.0.0:8000 --settings aws

10)
How to enable debug mode in selected setting
* Goto the settings file you selected. For example, if you given "--settings aws" in "runserver" command or if you are using "aws" setting, then goto /edx/app/edxapp/edx-platform/lms/envs/aws.py and make following flags "True" and restart the server

DEBUG = False
TEMPLATE_DEBUG = False

* Restart the server in debug mode using "./manage.py lms runserver".
#sudo -u www-data /edx/bin/python.edxapp ./manage.py lms runserver 0.0.0.0:8000 --settings aws

OR

* Restart the server in normal node
#sudo /edx/bin/supervisorctl -c /edx/etc/supervisord.conf restart edxapp:
