rails_admin 2.0.0.beta error: undefined method `per_page_kaminari'

[sedubois]

With rails_admin 1.4.2 I needed this initializer to avoid Kaminari pagination errors:

# config/initializers/_kaminari.rb
# Ref: https://github.com/sferik/rails_admin/wiki/Troubleshoot#conflict-between-will_paginate-and-kaminari
Kaminari.configure do |config|
  config.page_method_name = :per_page_kaminari
end

However, even though I have not touched this initializer, after upgrading to rails_admin 2.0.0.beta, the error comes back when visiting one of my PaperTrail model history admin pages:

undefined method `per_page_kaminari' for []:Kaminari::PaginatableArray
