I’ve got the same or similar issue using Jupiter theme. Site is set to full layout (thus no sidebar)
Forums do start on a Page, but otherwise exist in Posts which i dont see how to assign widgets/sidebars/template etc in order to facilitate navigation. So when clicking into the forum navigation, any sidebar items assigned to the forum root page, aren’t brought in. User has to user browser Back button to get back to root forum. I’m failing to get it to look and feel like forums are expected. i chose bbpress to have single sign on, but would welcome other options at this point or a direction in how to get different layout, sidebar navigation and such to show for bbpress forum posts. thanks in advance.
