I have tried updating, reinstalling bundle and removing 4.0.2 versions of activesupport, activeresource but didn't work. Because I've been fiddling around too much, even rails server doesn't work. Please help!!

Answer 1

I came across this other SO post which suggest doing the following:

$ gem install rails -v 3.2.13
$ gem install refinerycms

I then added Rails 4
