Got RoR running okay on my A2 hosting plan with radiant gem installed. Followed directions from [http://dev.radiantcms.org/radiant/wiki/Installation](http://dev.radiantcms.org/radiant/wiki/Installation) and get the following when the Radiant app starts. Any help is greatly appreciated: NameError uninitialized constant SiteController RAILS\_ROOT: …/config/… Application Trace | Framework Trace | Full Trace /usr/lib64/ruby/gems/1.8/gems/activesupport-1.3.1/lib/active\_support/dependencies.rb:123:in `const_missing' /usr/lib64/ruby/gems/1.8/gems/activesupport-1.3.1/lib/active_support/dependencies.rb:131:in `const\_missing’ generated/routing/recognition.rb:339:in `recognize_path' /usr/lib64/ruby/gems/1.8/gems/actionpack-1.12.5/lib/action_controller/routing.rb:511:in `recognize!’ /usr/lib64/ruby/gems/1.8/gems/rails-1.1.6/lib/dispatcher.rb:38:in `dispatch’ dispatch.cgi:10 /usr/lib64/ruby/gems/1.8/gems/activesupport-1.3.1/lib/active\_support/dependencies.rb:123:in `const_missing' /usr/lib64/ruby/gems/1.8/gems/activesupport-1.3.1/lib/active_support/dependencies.rb:131:in `const\_missing’ generated/routing/recognition.rb:339:in `recognize\_path’ /usr/lib64/ruby/gems/1.8/gems/actionpack-1.12.5/lib/action\_controller/routing.rb:511:in `recognize!' /usr/lib64/ruby/gems/1.8/gems/rails-1.1.6/lib/dispatcher.rb:38:in `dispatch’ dispatch.cgi:10 This error occured while loading the following files: site\_controller.rb
