Trying to switch domain from non www to www

Hi everyone,

I really need some help…I’m a noob :)

I installed a site on DO using easyengine. I am able to get Wordpress to install and add content and such.

When I go into WP admin and change the site from nonwww to www the site crashes. The nonwww version works fine and 301’s the www version.

I am trying to follow these instructions:

https://www.digitalocean.com/community/tutorials/how-to-redirect-www-to-non-www-with-nginx-on-ubuntu-14-04

Here is my problem. I followed the instructions. I opened up Putty, logged in and entered: sudo vi /etc/nginx/sites-enabled/default

After that loads, I get some white and blue text.

I enter :

server { listen 80; server_name example.com; return 301 $scheme://www.example.com$request_uri; }

Of course swapping out the example.com for my domain.

After I do that, I can’t figure out how to save the file.

I think that’s the last step where I get lost. Any advice would be greatly appreciated.

Thanks
