How to create new user roles and permissions
To restrict your users' access in the admin panel of your WordPress site, and control what changes they can make, create roles that outline their permissions and add users to those roles.
1. Go to Members plugin by MemberPress
2. Use the "Enter role name" field to add the role name. For example you could create a 'moderator' role for your blog.
3. Use the tabs on the "Capabilities" to go through the areas you want your user to access.
4. Use the "Grant" or "Deny" checkbox to set the permissions.
5. Click the "Add Role" button, once you are done.
Once the role is created, add users to the role.
