Hmm, it seems to be an issue with the Station theme itself. I edited the theme’s config_sidebars.php and added a new register_sidebar() call for “Content Sidebar”, and now I can see the sidebar. I’m curious if the sidebar is supposed to only be in the Pro version of the theme and the load accidentally made it into the free version. *shrug* Anyhow, that seems to have been what the problem is.
