theme Shoppingcart

Hi I hope you’re fine
I have difficulty with your theme shoppingcart which by the way is an excellent theme. My difficulty is that I can’t install the demon. And when I try to customize some widget only show up when I select. Compared to the home page I don’t understand why when I index static page in the settings. The page shows a white block containing the title and the logo but I appear at the bottom of the widgets. If I could install and activate the demon it would suit me a lot and I wouldn’t have to do a lot of tuning.
Thank you for your help !
