This works fine for me. From what version did you upgrade? Did you clear out the cache and recompile the assets?

sudo -u git -H bundle exec rake assets:clean assets:precompile cache:clear RAILS_ENV=production

Also, you probably want to update ruby to v2.1.6.

Updating ruby to 2.1.6 fixed the problem. Thanks!
