1) When using this plug-in on my localhost, I see options to manage 'Custom Capabilities' but this option does not show when I use this plug-in on my production server.
Both WP instances are using same version of WP and plug-in. I did however, used other plug-ins on localhost to manage the roles/capabilities, but those plug-ins are disabled now.
2) Also, on localhost, when logged in as admin, I see option to manage capabilities for all roles (including Super Admin) except Admin. But on production server, only levels below Admin are shown in the drop-down list.
