I have created an install using EE. I have done the multisite wordpress install with subdomains. The only way I have been able to set up the domains to work correctly has been through using the WPMUDEV domain mapping plugin. The standard one didnt work for me.
I can proceed, and there it shows me the correct site. I am trying to get a similar site up, but I will have a different domain pointed. I have had nothing but issues getting this to work on my server.
My config is an AWS EC2 with an elastic IP running ubuntu 16.04.
Thanks in advance
