Sidebar only showing on posts when logged into admin

I am using WP Soul, have added a google adsense unit to the sidebar.
My sidebar shows up on my home page (static page) and in my posts whilst I am logged into WP-Admin but when I log out and visit the site’s URL, it is not visible at all. It should be displaying recent posts, pages and beneath that the ad unit.

The Website address is https://www.bestpetrolhedgetrimmer.com – as you can see, the posts do not have a sidebar at all but the front page does. This is my first attempt at building a website.

The Theme Editor for single post has the get sidebar code in it so I am at a loss.

Help Please!
