Dashboard not Loading w/ out help

Hello. I found a theme and code on one of these forums called “Adaptive Mushroom”. I installed the theme manually and have everything up and running.

BUT…

The dashboard does not load right away. The only way I can get it to load is by going into the “Raw Config. editor”, changing something (anything) and then saving it. After that, it loads right away.

Any ideas?

I had the same problem and in my case I was able to solve it by removing the visible: - user: from the raw configuration of the dashboard
