First of all, thank you for creating such an easy way to manage sidebar display!
I have found an issue where the sidebar is not displaying on the individual post pages. All other pages, including custom post pages seem to be working fine. I have created a child theme based on the Mantra theme.
While investigating the sidebar issue, I switched to the parent theme, and found that the sidebars display just fine there. It's only when I switch to the child that they disappear. I tried removing all files except the required styles.css to see if any of my customizations caused the problem, but the sidebars are still not showing up.
Can you please help me resolve this issue?
