This is one of those plugins that you should have etched in your memory, ready to deploy whenever you need tweaking user roles / capabilities or, more importantly: RESET them all to their WP core defaults (i.e. deleting all but the standard fresh, vanilla install state) when you need to undo bbPress, BuddyPress, s2Member, Woocommerce, Simple:Press or somesuch plugin that creates custom roles and/or changes capabilities. It's simple, straightforward, logically presented... Awesome.
