Question: Why does the textfield doesn't follow the `.span1` rule? What can I do to fix it?

<head>
  <title></title>

<body>
  <div class="container-fluid">
    <div class="row-fluid">
      <div class="span12">
        <form class="form-horizontal">
          <fieldset>
            <div class="control-group">
              <label class="control-label" for="focusedInput">Focused input</label>
              <div class="controls">
                <input class="focused span1" id="focusedInput" type="text"
                value="This is focused" />
              </div>
            </div>
            <div class="control-group">
              <label class="control-label">Uneditable input</label>
              <div class="controls">
                <span class="span1 uneditable-input">Some value here</span>
              </div>
            </div>
          </fieldset>
        </form>
      </div>
    </div>
  </div>
</body>

A quick way to fix it is by changing `row-fluid` to `row`. But how do I fix it while still using the `row-fluid` tag?

Answer: 
It would be much more convenient to define allowed routes in routes.rb and add exception handling in application controller for routing error:

```
class ApplicationController < ActionController::Base
  rescue_from ActionController::RoutingError, :with => :render_not_found

  private
    def render_not_found 
      render_error_page_for(404)
    end

    def render_error_page_for(code)
      respond_to do |format|
      format.html { render :file => "#{Rails.root}/public/#{code}.html", :status => code, :layout => false }
    end
end

```
i do catch my exception handling in my application controller but unfortunately for admin\_data, i don't explicitly set it in routes.rb. it gets configured somewhere in the gem with namespace or something (im not really sure) 

but on a positive note... i finally fixed it! i changed my glob and did...

```
match '*not_found', to: 'errors#error_404', :constraints => {:subdomain => "!(admin_data.)"}

```

to ignore everything which uses admin\_data.
