When I select the sidebar option here I don't see anything in the sidebar, am I missing something else that needs to be done here?
If you use something which overwrites the default sidebar, such as a widget add on like Widget Franework then this is expected. The recent media block needs to be a widget. This guide may help you do that: https://xenforo.com/community/resou...media-block-to-a-sidebar-or-portal-page.3793/
