Rails & Heroku: We're sorry, but something went wrong - ruby-on-rails

I am getting the infamous "We're sorry, but something went wrong." error. Googling it it points to Omniauth problem - but I havent changed much (if any) of the omniauth stuff, and had it working last time I deployed it to heroku.
I have it deployed on a cedar stack btw.
Any ideas what the problem could be?

This seems really out of the blue, but what fixed my problem was having the haml gem within the assets group. I took it out from that particular group, and it fixed my problem. Not sure why.

Block in spawn_thread when deploying to Heroku

Recently, I implemented carrierwave into my Rails project to allow image uploads (using S3 for production) and I am now having difficulty logging in to my website. One thing to note is that my website does redirect to a page that relies on carrierwave, but I am not sure if this is the problem. Here is my result when I do heroku logs:

I don't really have a good sense of what is going wrong here. I see that in the middle there is a problem with warden, so it could be a problem with Devise, but it could also be a problem with my carrierwave. I have a default image that it is supposed to use if there is no image, and I am not sure if this has uploaded yet. Let me know if I need to post some more code or clarify to improve this question.

ActionView error when deploying to Heroku, works fine locally

I'm building a small app that uses the blazer gem - everything works fine until I try to create new query via "blazer/queries/new" and it gives me the following error. I can't seem to figure out the difference between production and local (works fine) that causes this error. I've eliminated ruby version, routing order, and asset recompilation, but have no idea what's going on. Thanks!

Figured it out - basically I needed to set my Blazer Environment variable within Heroku so I did this in the terminal:
heroku run rails c
> ENV['DATABASE_URL']
> *My Database URL*
heroku config:set BLAZER_DATABASE_URL=*My Database URL*
And it worked!

Heroku deployment issues - 500 Internal Server Error

I've searched all over stack overflow and the web and tried various fixes but I'm still unable to get my rails app running on heroku. I am consistently receiving the "We're sorry, but something went wrong." error from heroku.
The app runs fine in my local environment.
I've done the following:
Run "heroku rake run db:migrate"
Verified that my assets are being compiled correctly: https://devcenter.heroku.com/articles/rails3x-asset-pipeline-cedar
Implemented Thin server and created a procfile as referenced here: https://devcenter.heroku.com/articles/rails3
I would really appreciate your help in analyzing my heroku logs file (below) to figure out what's causing this error.
My app is running on Rails 3.2.7, Ruby 1.9.3 and uses postgres as the db

I continued my search for a solution on stack overflow and found my answer here;
Rails & Heroku: We're sorry, but something went wrong
I removed my "haml-rails" gem from the assets group (and platop of the file) and this fixed my issue.

How do I fix this mysterious Heroku error that has no specific error that I can identify?

Forgive me if this is a duplicate of another post, but I can't seem to identify anything in this error log that I recognize as fixable. Generally, the topmost error is something in my rails app, and something that I can address. In this case, I havent a clue.

Can't login using Devise on Heroku

I recently pushed my first app to heroku using their guide. (https://devcenter.heroku.com/articles/rails3) Everything went fine considering the push. Now I visited my app and tried to register, now the error 500 page turns up from my public folder every time I try to register or login.

gem 'easy_roles'
gem 'paperclip'
gem 'therubyracer'
gem 'activeadmin'
gem 'formtastic'
