The sidebar is not showing properly. The items are shown below the post when they should be shown on the right sidebar. https://spydrill.com/qustodio-review/
looks like there is some broken HTML on your single posts.
Have you added any code to the single post using the Hook Element ? e.g Author Box or Sign Up Form. If so can you disable them by Quick Edit and change the Status to Draft
I would like to increase the right sidebar width. But when I do so the content area becomes too small. But if I decrease the blank space on the left then it will look better.
