Update 6.3 -> 6.4: uninitialized constant Unicorn (NameError)
Created by: Pro
I followed the update guide on this site to update from gitlab 6.3 to 6.4: https://github.com/gitlabhq/gitlabhq/blob/master/doc/update/6.3-to-6.4.md
But now I get on both servers the following error when opening gitlab in the browser:
uninitialized constant Unicorn (NameError)

I updated gitlab.yml and unicorn.rb (which isn't mentioned in the update guide) but no luck.
