Reply To: Disable sidebar on product categories that are displaying only subcategories

Actually, with some of the Demos there are certain Custom Layouts enabled for the Single Product and Archive pages which is why your made changes under the Theme Settings aren’t taking effect on that.

Please disable the custom layouts from dashboard -> layouts and check the issue.
(I switced to wide layout and no change also)

If you want to use the custom layout try to create a new layout for specific categories and remove the sidebar in these categories layouts.
(Already done that with no success)
