[導入プラグインの有無] クロネコヤマト カード・後払い一体型決済モジュール 会員登録後に注文画面へ移動するプラグイン(3.0系) PAGE TOP プラグイン 配送伝票番号プラグイン おすすめ商品管理プラグイン 最近チェックした商品
[カスタマイズの有無] xserver簡単インストールにてインストール、脆弱性対応済み
[現象] クロネコヤマト　カード・後払い一体型決済サービス(3系)にてクレジットカード、コンビニ決済など当プラグインを使用した決済完了後、商品購入完了ページに移行する際に500 Internal Server Errorが発生します。
その状態から再読み込みを行うとeccubeからシステムエラーの画面に移り、トップページへ移行するとHPが一部分しか表示されなくなります。おそらく下記部分がエラーが出ている部分のログかと思います。

また、デバッグモードにて確認するとクロネコヤマト　カード・後払い一体型決済サービス(3系)プラグインに移ったページ（確認したのはカード決済選択時のカード入力画面）の時点でエラーになってしまいました。デバッグモードでない場合には正常にカード情報入力から手続きが完了し、上記の状態になります。こちらは以下のように表示されます

当方プログラム的なことが全く分からないために手の打ちようがありません。どうぞ皆様のお力をお貸しください。よろしくお願いいたします。
