ModPorter::InvalidSignature in ScreensController#create != 8rFPaOuZX6yzocNSh7d41b14VRE

We use Rails version - 2.1.1 and Passenger version - 2.2.4.
We had followed all the steps given in github to install modporter and make changes in the conf file.

However we got the following error.

Configure the plugin by providing the shared secret in application.rb :

class ApplicationController < ActionController::Base
self.mod_porter_secret = "secret"
end
