As tested on more than one side, if you want the sidebar layout on the left, it will cause pages with sections to glitch out, showing the body background or white color on the left side of the screen, and moving the content to the right, also widening the width of the website.
Just take a look, blog page displays left sidebar, as I set the layout Sidebar Content.
But go to Home, and look at the white space in the left … try it yourself on a website, it should’t be different, this happens to me on all websites… Is it just me ?
