You need to use the correct route as your controller is named MainController so your route should be "main#index". Your route file should have this code

Rails.application.routes.draw do 
 root 'main#index'
end

Check if you have a HomeController and if you don't have maybe it's just cached as it's showing blank page try clearing the cookies and reloading the page. (Works for me most of the times.)

You need to specify correct controller in your routes.rb file which is MainController, so it should look like this:

Rails.application.routes.draw do 
   root 'main#index'
end

It still unclear why the original would render a blank page instead of causing a routing error.
