Rails - Sep 2013 - Why does Rails debug information shows up in production?

I recently upgraded Bargain Stock Funds (http://www.bargainstockfunds.com) 
and Doppler Value Investing (http://www.dopplervalueinvesting.com) from 
Rails 3.2 to Rails 4.0.

I''ve noticed that the debug information is on the production web site
even
though the app/views/layouts/application.html.erb file has the line "<%=
debug(params) if Rails.env.development? %>".  This SHOULD suppress the 
debug information on each page in the production environment, but it 
doesn''t seem to be working.  (The technical tabs on both web sites
contain
the links to the source code.)

Commenting out the "<%= debug(params) if Rails.env.development?
%>" line
does remove the debug information, but I need to retain it in the 
development environment.  Thus, I believe that my production environment is 
being mistaken for the development environment.

My questions:
1.  How do I confirm whether I''m in the development or production 
environment?  My assumptions don''t seem to be holding up.
2.  What is the mechanism that specifies the development or production 
environment?

This tells me you are not running with RAILS_ENV=''production''.
Instead, it is either not set (defaults to ''development'') or
is set to ''development''.

You check Rails.env or ENV[''RAILS_ENV'']

The RAILS_ENV environment variable is set to the environment you want loaded. If
it is not set or empty, it defaults to ''development''.

I''ve done some troubleshooting and have confirmed that what should be
my
production environment is being seen by Rails as the development 
environment instead.

What is the proper way to make sure that my production environment is 
actually seen by Rails as the production environment?  Please keep in mind 
that I''m in Rails 4.0 and not 3.2 now.

I found out what the problem was.  The nginx.conf file in the production 
environment (which is automatically generated when I create the Rails 4.0 
app in WebFaction) specified the development environment instead.  I 
changed it to specify the production environment.  Now the production 
environment actually behaves like the production environment.
