Couldn't load QA_SITE_SETTINGS.APP_URL

edit

I have cloned askbot into list of apps folder in my existing django project. I synced the database and I can see all the askbot tables. When start my local server my website works but when I try to login I get this error

Exception Type: SettingNotSet
Exception Value:    
("Startup error, couldn't load QA_SITE_SETTINGS.APP_URL", None)
Exception Location: /Users/name/PycharmProjects/new/wizbot/website/website/configs/common/../../apps/askbot/deps/livesettings/values.py in _value, line 346

What is this error? should I add any live settings? Or is it because of the Users integration of askbot with my django project?
