Widgets not displaying in right sidebar

Hi guys, I started playing around with different widgets to go in the right sidebar, some widgets wouldn’t even display and when I put the original widgets back into the sidebar they didn’t display at all. Now I can’t get any widgets to display. Any ideas why even though the sidebar is showing with 3 widgets they won’t display in the view – https://supportlocalbusinesses.com.au/sample-page.
