No sidebars showing even with compatible theme

Because I was having trouble with LifterLMS in my custom theme, I created a subdomain for my courses, so I could use a compatible theme. I read that “Make” was compatible with LifterLMS.

So I got the Make theme specifically for this. I still cannot get any sidebars to appear on my course page.

I tried the SUper Sidebar Lab plugin and nada.
