Yeah its within

/var/www/example.com/src/khcards

so full path is

/var/www/example.com/src/khcards/wsgi.py

Andrew SB · Answer

Is there a wsgi.py file in you Django project? It doesn’t seem to be getting imported:


added /var/www/example.com/src/khcards to pythonpath.
ImportError: No module named khcards.wsgi
unable to load app 0 (mountpoint=‘’) (callable not found or import error)
*** no app loaded. going in full dynamic mode ***
