I feel silly, but I went through and disabled a bunch of the capabilities for "administrator", because that's the default role for users who sign up to create a new blog. After the changes went through, those options are now no longer showing up at all. I can't enable them for ANY roles, which is pretty inconvenient. I tried deactivating and even deleting and reinstalling the plugin, but they're not coming back.
...any ideas? And IS there any way to edit the regular admin role without interfering with the super admin?
