```ruby
class ApplicationController < ActionController::Base
  # Prevent CSRF attacks by raising an exception.
  # For APIs, you may want to use :null_session instead.
  protect_from_forgery with: :exception
  include Squash::Ruby::ControllerMethods
  enable_squash_client
end
```

Remove squash from app/controller because squash is not set up for the app
user
```ruby
class ApplicationController < ActionController::Base
  # Prevent CSRF attacks by raising an exception.
  # For APIs, you may want to use :null_session instead.
  protect_from_forgery with: :exception
  # include Squash::Ruby::ControllerMethods
  # enable_squash_client
end
```
