RIght on brothaman - thank you.
Yes, I did try... but was not confident in my results. I'm glad I double-checked with you... it makes me feel better to know that everything is setup correctly after reading your responses.
No issues at all, though, I switched from subdomain to subdirectory for a couple of reasons.
1. lack of wildcard support for LE SSL
2. I thought it was weird that I did not see any folder populated in /var/www/
The domain mapping works correctly and I just finished testing out things like adding a website, changing dns in CloudFlare to test map domain, activating plugins, etc... everything works great!
Ahhh... one thing I did notice, Nginx Helper Plugin.. when I had that activated with the one setting "Delete local server cache file" I would notice weird 1s or 1.5s bottleneck so I chose other radio option and that disappeared. I didn't notice anything weird when I configured Redis Object Cache Plugin.
What do you think about the SSL thing? If CloudFlare setting Crypto is set to Full, does it make a difference to run sudo site domain.com -ssl-on ? Does any magical setting in the nginx.conf file change?
