Rails - Oct 2013 - I think I've found a mistake in Rails tutorial

At the point of this section 
      
*http://ruby.railstutorial.org/chapters/sign-up#sec-signup_failure*<http://ruby.railstutorial.org/chapters/sign-up#sec-signup_failure>
clicking the "Create my account" button on the signup form shows the 
following image at 

<http://ruby.railstutorial.org/images/figures/signup_failure_rails_4.png>
According to the tutorial, I must modify these files to rid myself of the 
error.

   - app/controllers/users_controller.rb 
   - app/views/users/new.html.erb 
   - app/views/shared/_error_messages.html.erb 
   - app/assets/stylesheets/custom.css.scss 

I made all the modifications (until I saw the *working
image*<http://ruby.railstutorial.org/images/figures/signup_error_messages_bootstrap.png>to
the 4 files), and I still get the error image above when submitting the
file, rather than a page that shows me that I left the fields blank.
 
Can you help with this?

Please don''t use images, copy/paste the error and short segments of
code here.  First make sure you have checked the values of any
variables (params for example) by checking the values passed in
log/development.log and using puts to print values into the server
window.

Are you using exactly the versions of ruby, rails and gems expected by
the tutorial?

There is no params as I am just clicking a Signup button that''s on a
page,
then the error shows up.
I''m using Ruby 1.9.3 and the latest versions of sass-rails and
coffee-rails.

One should not claim a tutorial is broken before finishing it, because
clearly further down:

To add since I neglected to mention it like I should have, just
because your form is blank does not mean there are no params, blank or
not it will create a param as the form still sends the fields, that is
why you see them listed there with "". "" is not a null
value, it is
an empty value, empty != null, nil == null because even a blank value
is a value to all systems.  This is why Rails has .blank? and
.present? so you can work around this situation, but tbh you should
not need to as after you permit them and then pass them into the model
it should have already done a validator stating that you do not wish
it to be blank or null.
