Correctly setting up naxsi in LearningMode in Nginx

While activating naxsi for my set up that uses nginx as reverse proxy with gunicorn, I've run into a misbehaving piece of code. Can someone help?

For now, I'm trying to turn naxsi on in LearningMode. I've added the following in the http section of my nginx.conf:

include /etc/nginx/naxsi_core.rules;

Also, I've changed DeniedURL value in naxsi.rules. So far so good.

My problem arises where I'm supposed to edit /etc/nginx/sites-enabled/default" (as instructed in various online tutorials) to include include /etc/nginx/naxsi.rules; in root location.

My file in sites-enabled isn't called default, it's myproject. In sites-available though, I have default and myproject both (remember this, this has a role later in the question).

No worries so far. I add /etc/nginx/naxsi.rules; in myproject.

I next restart nginx via sudo service nginx restart. It fails to restart. I reverted. Then added the default file at /etc/nginx/sites-enabled/ (copied from sites-available/default), and added /etc/nginx/naxsi.rules; there.

Restarted again. Still failed. I reverted everything and restarted. The server is up and running, but I don't have naxsi.

What am I doing wrong? It's probably something basic.
