Membership and User Plugin

Evening WordPress Users

I have a Scout website, which I am trying to assign permissions to roles (i.e. Parents, Leaders etc.). These will open certain menus and give permissions for leaders of certain levels to have greater access (i.e. add posts, create events etc.) than say a parent that will be able to book on to events but not see the leaders areas.

I am not well versed at creating the roles permissions, and am currently using Ultimate Member as I thought this was the easiest to use. Unfortunately when I assign users to groups, and groups to pages or menus, they are not showing up on the site, when they should be.

Does anyone know of any easy to user, user and membership (preferably combined in one plugin) which I could use for my site.
