So, here is what I did:
1. I loaded the QuickStart files - thought that would be enough - wrong!
2. I switched to the Child theme - thought that would be enough - wrong!

I noticed there is a CSS file in the Child theme - may be I should import it somehow? O also downloaded that json file in the header of the forum thread - should I import it to have the Demo website like at https://www.gavick.com/wordpress-themes/education ?
