I published course but nothing shows up

The link above should show my course. However, nothing shows up. It says blank page. I published the course, I published the lessons, but I can’t find any of it when I try to view it.

The same is happening with the other pages. I have manually enrolled myself in the course, but nothing shows up on the dashboard page.

I checked to make sure that all the pages are published. Please, someone, help me because I need to make this work before I can buy the stripe add on and transfer my actual course over. This one is just a test, so I know how things work, but apparently, it’s not working out.
