Sidebar missing

I am trying to work on a custom theme. And for some reason the side bar is missing. And i’ve done every thing i can to fix it. The person who made it, their demo it shows the sidebar is working. But I’ve tried contacting them and I haven’t heard back. And I am getting annoyed. HELP

I don’t know if i am allowed to post this or if y’all can even see this but this is the theme.
