[Rails] Wierd ID problem controller router?

Hello, recently on one of y sites i have a weird ID problem one
editing some pages.

After edit I get an The page you were looking for doesn't exist.
error.

The Id of the editing page is 93 but in log files I have

ActiveRecord::RecordNotFound (Couldn't find Page with ID=403):
app/controllers/pages_controller.rb:44:in `show'

In the controller there is just
def show
@page = Page.find params[:id] # line 44

respond_to do |format|
format.html { render :layout => 'application' }
end
end

I'm really stunned by this error, I've looked in the source of the
edited page but it seems ok.
