You can delete administrators if you are a Super Admin.
You can remove administrators. Removing an administration role from a user doesn't delete the user.
To delete administrators, do as follows:
- Go to Global Settings > Role Management.
- Select the administrator role from which you want to remove users.
- On the role details page, next to Role Members, click Edit.
- In Edit Role Members, select a user in the Assigned Users list and use the picker arrows to remove them.
