Reply To: The sidebar is gone. Can’t find where it turns on

Hello,

This widget area is for the Shop / Product categories pages. WooCommerce filters and Product categories should be added here. In order to show the sidebar on the Shop page, it is necessary to set “Right” or “Left” in the Theme Settings – > Shop – > Sidebar and Titles.

Please check this manual:
