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 to ninja mode, you will be asked to add the code in nginx.conf file.

What you have to do is to add the code after “try_files $uri $uri/ /index.php?$args;” line. See the below example:

server {
        server_name [your domain name];
        root [path to the website root];
        index index.php;
        include path-to-file/hidemywp.conf;
        location / {
                try_files $uri $uri/ /index.php?$args;
        }

}

If you nginx has the sites-enabled option activated you have to enter in the sites-enabled subdirectory and open the file with the domain name. In that file you will find the above configuration.

Note: Don’t delete any line from your current configuration unless you know what you are doing.  

After you add the lines in your conf file, save it and go back to your Hide My Wp settings and press the “Okay, I set it up” button. Logout and check if the new URLs are set correctly by checking the source code.

Note: You need to reload the Nginx config to apply the changes.

For  linux use:

# nginx -s reload

For  Windows use:

# cd C:nginx
# nginx -s reload
