python - Internal Server Error with Nginx and uWSGI -

i'm trying host app using nginx on linode.com i'm stuck on uwsgi config.

i've used "getting started" guide , "wsgi using uwsgi , nginx on ubuntu 12.04 (precise pangolin)" guide , i've succesfully deployed nginx (got nginx welcome message in browser).

although above tutorial ubuntu 12.04 i've used 14.04.

the problem starts when got uwsgi configuration , 'hello world' python app. going location / in browser returns failed load resource: server responded status of 500 (internal server error) , nothing gets logged in server error.log. location /static works though , serves files without hitch.

i've tried many things , looked extensively fix on google , stackoverflow nothing, , i'm kind of frustrated right now.

thank help.

here config files (i've hidden domain , ip):
