新規インストールにてセットアップが無事に完了。
管理画面へアクセス→OK
ショップページにて商品一覧（初期登録商品2点）ページを表示→OK
商品詳細ページへアクセスすると、システムエラーが表示されます。
index_dev.phpで確認すると以下のエラーが表示されます。

そもそもWEBインストーラーでテーブルが作成されていないのか、よくわかりません。
他の質問も見ましたがアップグレードの方でした。
DBを新規に作り変えてもう一度最初からインストールした方がいいでしょうか？
新規インストールする際は、public_htmlフォルダ以下を全て削除してから新規インストールしております。
どなたかご教授お願いします。。。

最近見た商品プラグインが設置してあるがインストールしていない状態でしょうか？

インストールするか、プラグインのファイルを取り除くとどうでしょうか？

EC-CUBEカスタマイズ・高速化・脆弱性対策・SEO ご相談ください。

2系・3系から4系へのバージョンアップ実績豊富

ありがとうございます。
プラグインが何故か消えてなかった様子です。
消すと無事に表示され、カートに入れる事ができ、お買い物が完了しました。
ただ何故か自動送信メールが送信されない？別のトラブルに見舞わられております。。。。。

購入のメール送信メソッド内にlogを仕込んでみてはいかがでしょうか。
logを仕込めば、そもそもメール送信処理を通過しているか、どのようなデータを持ってメール送信処理を通過しているかわかるかと思います。
