I'm working with a rails application I've been using for a very long time that has not had a front end prior to this point. By long time I mean over a year. I use it to run console-based database stuff.
I'm trying to put a simple front-end on it now, a json api, but have been unsuccessful so far because of this error when trying to visit the homepage, users#index, or localhost:3000. Here is the error (including the webrick startup information because there are some warnings):
=> Booting WEBrick
=> Rails 4.0.0 application starting in development on http://0.0.0.0:3000
=> Run `rails server -h` for more startup options
=> Ctrl-C to shutdown server
config.eager_load is set to nil. Please update your config/environments/*.rb files accordingly:
* development - set it to false
* test - set it to false (unless you use a tool that preloads your test environment)
* production - set it to true

Here is my Gemfile. I've frozen my rails version due to new versions of rails breaking some of my code.
source 'https://rubygems.org'
gem 'nori' #XML TO JSON
gem 'rubillow'
gem 'rails', '4.0.0' #locked version May 25, 2015

Here is my routes.rb file, pretty vanilla:
PostgisRails::Application.routes.draw do
#resources :users
root :to => "users#index"
end
I've checked out similar error messages to this on SO but haven't found anything quite like my situation, i.e. a situation where everything is so vanilla/default.
I'm thinking the error is having to do with some code getting inherited or mixed (monkey-patched) in with ActionController somewhere in my massive codebase. However, all of the monkey-patches I've done that I know of are in my initializers folder, and I've temporarily removed that and still got the error.
Let me know what additional information you need and I'll provide it. Thanks
Additional Information
rails s to start the serverHere's my application.rb file
require File.expand_path('../boot', __FILE__)
require 'rails/all'
require 'highline/import'
require 'active_record/connection_adapters/postgis_adapter/railtie'
if defined?(Bundler)
Bundler.require(*Rails.groups(:assets => %w(development test)))
end

config.active_support.escape_html_entities_in_json = true

I added config.eager_load = true to application.rb and got an immediate crash when trying to start the server before I even tried to visit the homepage. Here's the stack trace for that.
=> Booting WEBrick
=> Rails 4.0.0 application starting in development on http://0.0.0.0:3000
=> Run `rails server -h` for more startup options
=> Ctrl-C to shutdown server

Please check that your helpers in app/helpers folder are all modules not classes, example:
app/helpers/application_helper.rb should be:

end
not

end
Also if you're including something in your classes Concern for example it should be defined as a module not class
