Apache Install not working

I have my server running 18.04 and followed the instructions to the dot

from here https://www.linode.com/docs/websites/hosting-a-website-ubuntu-18-04/#web-server

and I got to editing Apache's config file. I pasted what they said to at the end of the file. When I go to restart apache I get an error.

Nov 21 02:52:56 localhost apachectl[29483]: Invalid command '…', perhaps misspelled or defined by a module not included in t
N

so i'm assuming its a formatting error from the wiki… any ideas how to fix it?
