Rails on hosting server upgraded to 2.3.5 and my app broke

Please note that the "1" in the URL is not action id or session id but
the category or page id stored in database.

The error log says:
[code]
Processing ApplicationController#index (for xxx.xxx.xxx.xxx at
2010-12-19 09:32:18) [GET]

ActionController::RoutingError (No route matches "//pages/1/display"
with {:method=>:get}):

Rendering /home/hof/etc/rails_apps/ha/public/404.html (404 Not Found)
[/code]

hmmm. I've never seen such error before, a bit lost.

Here is my route.rb:

[code]
ActionController::Routing::Routes.draw do |map|
  map.resources :users

  map.resources :notifications

  map.resources :pages, :member => {:display => :get,
                                    :display_free_style => :get}

  map.resources :events, :collection => {:display => :get}

  map.resources :subcategories

  map.resources :categories #, :has_many => :subcategories

  map.root :controller => "hof"

  map.connect ':controller/:action/:id'
  map.connect ':controller/:action/:id.:format'
end
[/code]

rake routes shows the following result:

here is the pages_controller.rb:

  def index
    @pages = Page.find(:all, :order => "category_id")

    respond_to do |format|
      format.html
      format.xml { render :xml => @pages }
    end
  end

  def show
    @page = Page.find(params[:id])

  end

    if (@@free_layout_pages.include?(@page.subcategory.name_en))
      redirect_to :action => "display_free_style"

I just quickly read through the release notes of rails 2.3. But did not
get any clue about what I should change to get my app running again. I
must have missed something but don't know what.

Could anyone please give me a hint? Any help will be highly appreciated!

Best Regards,
Lydia

Please note that the "1" in the URL is not action id or session id but
the category or page id stored in database.

There is a lot of useful information you could have given us. Did it
display the index page ok at this point?

ActionController::RoutingError (No route matches "//pages/1/display"
with {:method=>:get}):

What did you click to make it show this, if anything?

Colin, thank you very much for taking the trouble to reply. No it does
not even display the index page. I just found out that the index page
which appeared was a cached fake. Maybe the admin of my host provider
put it there, but I don't know. When I renamed that index.html, I got an
immediate 404 and my app production log says:

ActionController::RoutingError (No route matches "//" with
{:method=>:get}):

Best Regards,
Lydia

Does it work ok in development mode on your local PC and pass all your
automated tests?

Colin
