Rails を使い始めたばかりで、サーバーを 2 回目に起動するようになったのですが、次のようなエラー メッセージが表示されます。/config/initializers の Ruby ファイルも変更していません。

config/initializers/session_store の内容は以下です。
# Be sure to restart your server when you modify this file.
Blog::Application.config.session_store :cookie_store, key: '_blog_session'
# Use the database for sessions instead of the cookie-based default,
# which shouldn't be used to store highly confidential information
# (create the session table with "rails generate session_migration")
# Blog::Application.config.session_store :active_record_store
