Fix 404 not found error in WordPress on NGINX

If your VPS or Linux server is using NGINX as the webserver running your WordPress website, you are probably missing the rewrite path configuration for your NGINX website. To configure the rewrite for WordPress on NGINX, enter the following into the domain configuration file in NGINX on the server.

location /
{
	 try_files $uri $uri/ /index.php?$args;
}

And remember to restart NGINX with the command service nginx restart
