[導入プラグインの有無] 配送方法設定拡張プラグイン for EC-CUBE4.0～4.1
[カスタマイズの有無] 無
[現象]

配送方法設定拡張プラグイン導入を進める中で、プラグインの設定(歯車マーク)や導入した際に追加された項目を押すと「ページがみつかりません。」となり、設定ができずそこから先に進めることができません。

キャッシュクリアや導入前の状態に戻し、コマンドラインにてプラグインインストールを試みたのですが結果は変わりませんでした。
メモリに問題がある可能性も考え、php.iniにてmemory_limitも上げてインストールしてみたのですが同じく先に進めることができませんでした。
