Rails not loading precompiled assets

I’ve just launched my first app, its running on Nginx and Unicorn.

For some reason although I precompiled the assets, they’re not showing
the browser.

Its showing all the css and js files instead of the precompiled

Would anyone have any idea what may be causing that. Could it be an
in my nginx or unicorn files?

Am running Rails 4 with Ruby 2 on Nginx and Unicorn. Assets under
/app/assets show in production, but for some reason the app is not
the precompiled assets in the public folder.
