Template is missing

I meet a strange problem, my application works well on development
environment, but when I switch it to production environment, a strange
problem of ‘Template is missing’ ,which have troubled me for several
days.

following is my code:

1.routes.rb:
map.index ‘’, :controller => ‘web’, :action => ‘index’
map.namespace :admin do |admin|
# Directs /admin/products/* to Admin::ProductsController
(app/controllers/admin/products_controller.rb)
admin.resources :users,:categories
end
map.connect ‘:controller/:action/:id’
map.connect ‘:controller/:action/:id.:format’

2.app/controller/admin/users_controller.rb
class Admin::UsersController < ApplicationController
layout “administrator”
before_filter :authorize

def index
@users = User.paginate :per_page=> PER_PAGE,
:page=>params[:page]||1,
:conditions =>[“login_name like ? “,”%#{params[:login_name]}%”],
:order=> ‘created_at desc’
end

def new
@user = User.new
end

end

3.app/view/layouts/administrator.rhtml:

<% if flash[:notice] -%>
 <%= flash[:notice] %>
<% end %>
<%=@content_for_layout%>
...

4.app/view/admin/index.html.erb is existed.
5.app/view/admin/index.html.erb is existed.

When I first browse ‘http://localhost:3000/admin/users’, it works, but
when I click the link ‘http://localhost:3000/admin/users/new’ on the
page, the error appeared.following is the information:
"Missing template admin/users/index/new.html.erb in view path
C:/rails-projects/school/app/views
".
when I removed the code “layout ‘administrator’” in users_controller.rb,
it works. but why?? It puzzled me.I can’t find which part is wrong
between template and routes. can u give me the answer?

Could anybody help me??
Did I explain the problem clearly?
I will appreciate your replay very much.

Try renaming your administrator.rhtml file to administrator.html.erb
