If your sidebar isn’t showing in Presidio, check these three areas below:
1. If you are editing your widgets in the Customizer, try going to Appearance > Widgets instead to see all available widget areas. The Widgets tab in the Customizer is a default in WordPress, and for some reason it doesn’t always show all available widget areas. We also find that it’s easier to edit Presidio’s many widget areas on the Widgets page instead as you can expand them all at once and see the instructions for each, as the 3 sidebar sections show based on how many interstitials are active, if any.
2. If you aren’t using interstitials, ensure that you are only placing widgets in the Sidebar Main widget area, as this is the only sidebar that will show on the home page without interstitials active.
3. Go to Settings > Reading and check your “Blog pages show at most” number. This number must be less than or equal to the total number of posts you have published in order for any sidebars to show. Because of the many display options in Presidio, the theme has to run a check on the last post per page in order to display the last (or main) sidebar.
