Deploy Ruby on Rails on Ubuntu 14.04 with Apache/Passenger

Question

I'm trying to deploy my ruby on rails application on a DigitalOcean server. I am using Ubuntu 14.04 x64, Passenger 5.0.10 and Apache 2 to deploy. I followed this tutorial. When I try to run my application on production environment I get this error "We're sorry, but something went wrong. We've been notified about this issue and we'll take a look at it shortly." I can run on development environment.

This are the Apache 2 access.log:
