We'll create fresh WordPress site with Multiple Roles installed. You have 20 minutes to test the plugin after that site we'll be deleted.
This plugin allows you to select multiple roles for a user – something that WordPress already supports “under the hood”, but doesn’t provide a user interface for.
User edit and Add new user screens will display a checklist of roles instead of the default role dropdown. The main user list screen will also display all roles a user has.
It also supports well Multisite mode.
That’s it. No extra settings.
