Right Sidebar Gone

https://khoifush.com/freeze-friday

Here’s an example of one of my problems. When I am signed into wordpress and then select the ‘customize’ icon, I am able to see my right side bar that shows: ‘search’ and ‘recent posts’.

However, when I am signed out or even when i am signed in without the customize tab, I am unable to see the right sidebar as apparent in the link.

Thanks for your help in advanced.
