Add a user to edit the layout of a site

We may need a little more information on the version of WordPress you are running, or at least the interface you are seeing that the new admin is not seeing. Typically, when I troubleshoot WordPress installations and I have to add an administrator, I have full access just like an admin. So, it shouldn’t be any different for you. Make sure that the role of the user that you add is set to Administrator.

If my answer doesn’t help, please provide us a little more information about the issue and we’d be glad to investigate it further.
