Ruby on Rails "NoMethodError" with no information

ANSWER IN FINAL EDIT

I'm running a project using Rails 3.1.3. I only have one page web page and my application contoller looks like this:

class ApplicationController < ActionController::Base
protect_from_forgery

def index
end

end

and a route

root :to => 'application#index'

in routes.rb.

When I load the page I get this error in a body:before html tag at the top of my page (otherwise the content seems to load fine)

NoMethodError: You have a nil object when you didn't expect it! You might have expected an instance of Array. The error occurred while evaluating nil.[]

Nothing shows up in my console where the server is running, and there is no information about where the error occurs.

As you can see, I have no idea where to start looking for this nil instance. Can anyone give me an idea of what might be going on here?

Edit: including the contents of my routes.rb file

ProjectName::Application.routes.draw do

root :to => 'application#index'

end

FINAL EDIT:

I had the project running in a different folder and recently moved it over. Turns out compass was throwing an error (thus why it was being thrown into my body html tag) despite loading the stylesheets fine. I needed to run compass clean then compass compile, I guess to make Compass aware of the new path. Thanks for the help everyone!

btw here is my Gemfile

source :gemcutter

gem 'rails', '3.1.3'

gem 'sqlite3'

gem 'json'
gem 'rails_config', '0.2.4'
gem 'jammit', '0.6.5'
gem 'compass', '0.11.3'
gem 'haml', '3.1.2'

gem 'jquery-rails'

I don't think that it is good idea to have any display methods in ApplicationController. Try run 

rails g controller welcome

and there add your index and route to this by

root :to => 'welcome#index`

EDIT After posting your Gemifile I saw where is problem. It's caused by that Comapss 0.11 isn't compatible with Rails 3.1. You must use alpha release. Change Compass version to:

gem 'compass',      '~> 0.12.alpha.0'

Perhaps it's occurring in index.html.erb file. Please, check if you are running on development environment, instead of 'production.' Then check the development.log file.
