Here's the issue. I created a number of customer user roles awhile back, with a previous version of this plugin--about three months ago. Now, when I go to the user role editor, I find that when I create a NEW user role, it shows up for other plugins, but the ones that I have now do not.
I tried creating copies of new roles, with the intention of deleting the old ones afterwards. Problem now is--none of the defined roles are showing under the "Remove Role" dropdown in the plugin settings page. So I can't delete them.
I tried editing the serialized data in wp_user_roles, even very meticulously and with a fine-toothed comb, but it screws things up every time.
I also tried optimizing and repairing my database, re-installing wordpress, deactivating, deleting and reinstalling the plugin... not sure what other options I may have here. Please advise.
