Also note that if you enable config.threadsafe, it will turn cache_classes on. So if your config/environments/development.rb file contains the following:

config.cache_classes = false

Then you are turning off cache_classes and then turning it right back on. You will need to either comment out config.threadsafe (if you don't need it) like this:

config.cache_classes = false
# config.threadsafe!

Or, if you need threadsafe, reverse the order of these two configurations so that config_classes is really turned off:

config.threadsafe!
config.cache_classes = false
