[PHP] 5.3.19
[DBバージョン]　MySQL 5.0.82-community-log

お世話になっております。
先日、パラメータ設定を変更していたら内部サーバーエラーがあり、原因不明だったためEC-CUBEを再インストールしました。
原因はDBの「mtb_constants」にあった模様で、そこだけ再インストールした際に作ったDBのままにし、他の物はバックアップを取ってあったものを使用しています。

しかし今度は、プラグインに異常があり管理画面から「プラグイン管理画面」に行くと元々インストールしていたプラグインの情報はあるものの、それぞれのプラグインの画像（機能説明の左側のサムネイル？画像）が表示されていませんでした。
使えるものだろうと思い、確認するために「有効」のチェックを外そうとしたら「●●.php」が存在しませんと言われました。

そこであまりやってはいけないことだと分かっていましたが、DBのプラグインの部分を再インストールしたものをインポートすると、プラグイン管理画面からプラグインが消えました。
その状態からプラグインをインストールすると以下の状態になりました。

○パンくずリスト
有効化はできるものの、レイアウトを適用させてもサイトにパンくずリストが表示されません。

○mdl_paypal
「SC_Helper_Plugin_PaypalWebpayment.php にdisableが見つかりません。」と警告されます。
また機能説明の左側のサムネイル？画像も表示されていません。

○最近チェックした商品
「有効化」にチェックを入れようとすると「システムエラーが発生しました。大変お手数ですが、サイト管理者までご連絡ください。」と表示され、ログインページに飛ばされます。


調べたところ「php_xmlというものが入っていれば「dom」という一覧が表示されるはず」とあったので、試してみたところ「dom」の表示はあったのでこちらは入っているようです。

余計なことをしてしまい、意味不明なことになってしまいましたが解決させたいので、解決方法をお教えいただければと思います。
よろしくお願い致します。

また、以下はエラーログです。

度々すみません。
先程投稿したものですが、PayPal以外は解決しました。

EC-CUBEを再インストールした際に、本番でもしまた何かしたら怖いと思いテストサーバーを作り、テストのテンプレートを作ってサバーエラーの原因究明を行いました。
その際に作ったテンプレートを本番でも使っていたので、別名のテンプレートだったので、サーバーエラーが起こる前に使ってたプラグインが使えなかったみたいです。
※テンプレート名を同じにしたらPayPal以外は使えるようになりました。

ただしプラグイン画面のPayPalは先程書いたのと同じ状況で、決済画面に行けるかも実験してみたところ「Your payment can't be processed. Please contact the merchant directly.」と表示されてしまいます。
本人確認も終了し、API署名も発行し記入しました。

可能であればアンインストールして、再インストールしたいのですが、それも不可能なようなのでこちらの解決策などありましたら、教えてください。
よろしくお願いします。
