2016/04/16現在、WordPress 4.5にアップデートしたところ、Child Pages Shortcodeプラグインでエラーが出るようになってしまった。
Apacheのエラーログを確認すると以下のようなメッセージが連発していた。

上記ログからChild Pages Shortcodeが怪しいと考えた。
Child Pages Shortcodeは、固定ページ内で、子ページの一覧を自動で美しく整形して表示してくれる優れたプラグインであり重宝していたが、仕方がないので同種のプラグインを検索したところCC Child Pagesというのが見つかった。
こちらのプラグインに変更したところ上記エラーが出現しなくなり、子ページも正常に表示されている。
なおChild Pages ShortcodeとCC Child Pagesは全く同じ[child_pages]という名前のショートコードを使用するため、乗り換えは楽であるが、共存させるとバッティング必至である。
WordPress 4.5にアップグレード後からApacheのレスポンスが経時的に遅くなり、再起動するとまた速くなるという現象を繰り返し始めたため、Apacheのエラーログを調べたところこの問題を発見した。
