I downloaded the RTFM Site Skeleton package to my local Mac development machine. It works fine. I installed the admin plugin. I want to change the default site title "Grav" to my site title, "Altoplace". I made the change in user/config/site.yaml, but the site title still shows Grav. I had done the same when using the Antimatter theme, and it worked fine.
What am I doing wrong?
