C:\Users\xxxx\Documents\Sites\simple_cms>rails s

Can anybody help me fix this?
PS: I am running on Windows 10
Try adding this line to your Gemfile
gem 'rack', '~> 1.6.4'
and then run:
bundle install
and see if that fixes your issue.
If the above does not work, try uninstalling railties gem. Then install an older version of the rails (rails version 4.0.0 was used in the from the tutorial). The issue is due to the version mismatch/incompatibility of some of your gems.
