A couple of things:
2014-09-05T04:56:15.594411+00:00 app[web.1]: Your Gemfile lists the gem pg (>= 0) more than once.
2014-09-05T04:56:15.594425+00:00 app[web.1]: You should probably keep only one of them.
You need to remove the duplicate mention of the pg gem from your Gemfile. I don't know precisely how to do this for your Gemfile because I can't see it. You're the boss here.
Next, as the comments have mentioned, your Contact model has a syntax error. You need to fix this.

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 Application Error: understanding the logs

I just pushed my rails app to Heroku. Then I ran heroku db:migrate then heroku db:push. But when I open the app I get the error "An error occurred in the application and your page could not be served. Please try again in a few moments. If you are the application owner, check your logs for details".
So I ran heroku logs and this is what I get:

I can barely make any sense of this files up here. Is there anything I might be doing wrong? I'm using Rails 3.2 and I already made sure I used heroku --stack cedar because I read somewhere that heroku only supports Rails 3 on the cedar stack.
--UPDATE--
As requested by Leo Correa below is a snippet of my users_controller.rb
def signed_in_user
unless signed_in?
store_location
redirect_to (signin_url, notice: t("user.please"))
end
end
That seems like a syntax error and you might be missing something like a curly brace or parenthesis
/app/app/controllers/users_controller.rb:54: syntax error, unexpected tSTRING_BEG, expecting keyword_do or '{' or '(' (SyntaxError)
2013-05-10T17:13:21.460325+00:00 app[web.1]: redirect_to signin_url, notice: t "user.please"
That chunk gives it away. So somewhere in your users_controller on line 54. Try doing this
redirect_to(signing_url, notice: t('user.please'))
I think it's problem of assets pre compiling you need to add config.assets.initialize_on_precompile = false in config/application.rb. If it is added in config/environments/production.rb
From your log it seems syntax error like:
redirect_to(signing_url, notice: t('user.please'))
I think you are using Devise Gem Check your code.
You might using free account of heroku. When you are using free account of heroku you can use only 18 hours a day and then automatically goes to sleep state or gets exhausted. When it happens you will get this error page. Try to skip the account to hobby type if your site busy.

I've been trying succesfully deploy my app!
Went on my site and it says the annoying old application error,
so i checked my logs and this is what I see

Make sure the plugin you are using is properly loaded and listed in your Gemfile.

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
2012-08-28T05:57:24+00:00 app[web.1]: DEPRECATION WARNING: You have Rails 2.3-style plugins in vendor/plugins! Support for these plugins will be removed in Rails 4.0. Move them out and bundle them in your Gemfile, or fold them in to your app as lib/myplugin/* and config/initializers/myplugin.rb. See the release notes for more on this: http://weblog.rubyonrails.org/2012/1/4/rails-3-2-0-rc2-has-been-released. (called from <top (required)> at /app/config/environment.rb:5)

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.
