title: Devise 404 errors on production server, No route matches {:controller=>"devise/home"}
body: <p>I'm getting devise 404 errors on a production server, both for get requests to /users/sign_in and its "link_to" equivalent.  If I copy development.rb to production.rb, I get the error:</p>
  
  <p>No route matches {:controller=>"devise/home"}</p>
  
  <p>This: </p>
  
  <ul>
  <li><p>Works on my development box.</p></li>
  <li><p>Doesn't work on the production box using either webbrick or passenger.</p></li>
  </ul>
  
  <p>All other routes are working OK, but the devise routes are not.  I think I've read every stackoverflow and other google-fu link I can find twice, but no luck so far.</p>
  
  <p>"Rake routes" output is below.  If I try the route that /users/sign_in GET resolves to, (i.e., devise/sessions#new), I get the error:  No route matches [GET] "/devise/sessions"</p>
  
  <p>None of the following work:</p>
  
  <p>link_to('Login / Register', new_user_session_path)
  link_to('Login / Regsiter', :controller => "devise/sessions", :action => "new")
  link_to('Login / Regsiter', :controller => "/devise/sessions", :action => "new")
  link_to('Login / Register', '/users/sign_up')</p>
  
  <p>I've seen some references to scoping issues, but I'll be darned if that makes any sense to me given the symptoms.  I'm completely stumped on this one.  Any ideas?</p>
  
  <p>Contents of routes.rb and "rake routes" output follow:</p>
