(solution) .js and .css error when using production environment

When changing to a production deployment with a single rails instance, NOT proxied, errors showed up on the console, and of course .js and .css files were not served as a result:

ActionController::RoutingError (No route matches "/javascripts/application.js"):

ActionController::RoutingError (No route matches "/favicon.ico"):

Solution: in config/environments/production.rb:

  # Disable Rails's static asset server   # In production, Apache or nginx will already do this   # config.serve_static_assets = false

The key is to comment the third line.

I know: using Mongrel for production isn't recommended, to say the least. I'm just posting the info so if you try it, you'll know why it's behaving differently.
