If your server is a Linux server, the main path to the nginx.conf file is /etc/nginx/nginx.conf (or /etc/nginx/conf/nginx.conf if you’re using Arch Linux). If the server is a Windows server your nginx.conf file will be located at C:nginxconfnginx.conf)
If your nginx doesn’t have sites-enabled option activated (check for sites-enabled subdirectory in the same directory with nginx.conf file), you will find the server configuration in nginx.conf file like in the below example:
server { server_name [your domain name]; root [path to the website root]; index index.php; location / { try_files $uri $uri/ /index.php?$args; } }
Now, if you change the settings in Hide My WordPress Ghost to Ghost Mode, you will be asked to add the code in nginx.conf file.
