I have added domains to control panel like : http://prnt.sc/e1uxue
However when I open my website : talkingsparrow.com or www.talkingsparrow.com
just a file get downloaded to my system.
Please let me know if I'm missing something.
You'll need to properly setup your NGINX server blocks for each website and make sure PHP is being handled in each one of the, else you may run in to issues such as the one your describing.
To get a more detailed look, I'd need to take a look at your website server block, which can be found within /etc/nginx/sites-available.
some more info : I have moved my wordpress blog from Apache to NGINX. , ubuntu 16.04 LEMP stack
Now not working even with www.
