Can I rename a role or delete one I no longer use?

Yes. Go to Settings → Roles & Permissions → Manage Roles.

To rename a role:

1. Click Permissions next to it.
2. Change the Role name at the top.
3. Click Save role.

To delete a role:

1. Click Delete next to it.
2. Confirm.

Before deleting, go to Manage Staffs and give anyone using that role a different Role. Otherwise they may lose access to parts of the admin.

To create a new role, type a name in New role name and click Add role, then set its permissions.
