Devise Sign Out/Log Out not working with Rails 4

Question

I hate to post another topic about this since there seem to be about a dozen but I can't find any that solve this issue for me.

In my application.html.erb I have:

<% if user_signed_in? %>
    Logged in as <strong><%= current_user.email %></strong>.
    <%= link_to 'Settings', edit_user_registration_path %> |
    <%= link_to "Log out", destroy_user_session_path, method: :delete %>
  <% else %>
    <%= link_to "Sign up", new_user_registration_path %> |
    <%= link_to "Log in", new_user_session_path %>
  <% end %>

routes look like this:

devise_for :users, 
    path_names: {sign_in: "login", sign_out: "logout"}
  resources :users
  resources :addresses

  root 'users#index'
  get 'dashboard', to: "users#dashboard"

And my local log looks like this:

started GET "/users/logout" for 127.0.0.1 at 2013-10-21 17:47:21 -0700
Processing by UsersController#show as HTML
  Parameters: {"id"=>"logout"}
  User Load (0.2ms)  SELECT "users".* FROM "users" WHERE "users"."id" = 1 ORDER BY "users"."id" ASC LIMIT 1
  Rendered users/show.erb within layouts/application (1.2ms)

So like many other topics, it's trying to pass logout as the id. I have the :delete in my application.html.erb link, so that's not it.

This is what's in my application.js:

//= require jquery
//= require jquery_ujs
//= require_tree .

That looks good.

Any ideas? I'm stumped...
