thanks for answering. Sorry, I had not much time in the last few days.
I've changed the files and commented out the content of /etc/nginx/sites-available/baruwa.conf.
But when I restart nginx and uwsgi I get this:
Restarting nginx: nginx: [emerg] unknown directive "[uwsgi]" in /etc/nginx/sites-enabled/baruwa.conf:25
nginx: configuration file /etc/nginx/nginx.conf test failed
Do you know what I did wrong?
