Why does my Heroku app give me an application error when trying to open it? Error with mongoid.yml file?

I am using locomotive CMS and have created an app with their engine and have followed all the steps to upload it to Heroku. However, when I try to open the app using my URL, I get an application error that says that "An error occurred in the application and your page could not be served. Please try again in a few moments." Below is the log details. Can someone tell me what is going wrong?

You have an extra space before uri which causes your yaml to be invalid. You can check it at http://yamllint.com

How to get rails app to work in production [heroku deployment]

In short: My application works fine in development using Devise, however in production I'm getting the error shown below. Bare in mind that I am using KatanaCode's BlogIt engine but I have re-built the user model, and schema and it is only using Devise's model.
github: https://github.com/Apane/Blogit_blog
Please advice.

Heroku website crashes with Rails 3.2.9 and route constraint

My website, hosted in Heroku, has been working fine with Rails 3.2.8. I'm using a route constraint class with the HighVoltage gem for static (mostly) webpages:
routes.rb:
get "/*id" => "high_voltage/pages#show", constraints: Constraints::StaticPage.new
I have a file in /lib/constraints/static_page.rb:
module Constraints
class StaticPage
def matches?(request)
File.exist? file_path(request.path)
end
private
def file_path(view)
static_page_views_dir.to_s.concat("#{view}.html.erb")
end
def static_page_views_dir
Rails.root.join('app', 'views', 'pages')
end
end
end
Problem is, I just updated to Rails 3.2.9 and did a git push heroku and my app crashed :(
my-host:my-site scott$ heroku ps
=== web: `bundle exec rails server -p $PORT`
web.1: crashed 2012/11/14 12:14:41 (~ 2s ago)
Apparently, Ruby/Heroku can't find my Constraints::StaticPage class. I have it required at the top of my routes.rb:
require 'constraints/static_page'
Did something change in Rails 3.2.9 so that no longer works with Heroku? Locally everything works fine, just not in Heroku. If I take out that constraint in my route, everything works perfect (aside from not having those constraints). Here's my heroku logs output:

Can you try out the following versions in your Gemfile:
# Gemfile
gem 'rails', '3.2.9'
gem 'high_voltage', '~> 1.2.1'
gem 'thin'
# ...
The 1.2.1 release of High Voltage has the root route constraints baked into it. This will allow you to remove the routes completely from your config/routes.rb file.
Just set up an initializer for High Voltage:
# config/initializers/high_voltage.rb
HighVoltage.route_drawer = HighVoltage::RouteDrawers::Root
I deployed the above to a Cedar app on Heroku and it ran as expected.

Keep getting 'Error H10 (App crashed) -> GET' when trying to deploy to Heroku

So I've been trying to deploy a rails app to heroku and have been having some issues. I did a good amount of poking around through the logs and on SO but couldn't find anything to point me in the proper direction. Then again I just might be missing something obvious. Anyway any help would be greatly appreciated.
Command
git push -f heroku master

I had to remove part of the logs for it to format right and be readable, its a deprecation warning

I believe the problem is in this line of the log:

Maybe the gem that you use to manipulate uploads and files is not installed. And remember that you can't use this gem without uploading your files to another server.

LocomotiveCMS and Heroku - deployment issues

I followed the instructions for deploying a locomotivecms app to Heroku:
http://doc.locomotivecms.com/installation/heroku
heroku open command brings up an error page in the browser. heroku logs reveal following:
