ゲストさん、こんにちは。

以下から続くスレッドが参考になるかと思います。
【告知】EC-CUBE 2.0.1正式版をリリース致しました。

apogee様

早々にご返答いただき有難うございます。

＞以下から続くスレッドが参考になるかと思います。
＞【告知】EC-CUBE 2.0.1正式版をリリース致しました。

上記スレッド内でかかれていたPostgreSQLを利用する手があるとのことで試しました。
無事に解決いたしました。

ただ、商品を登録するのですが、フロント側にカテゴリと商品情報表示されないのですが、商品検索後、価格順をクリックすると商品が表示されるという不思議な状態になってしまいました。

ちなみに、商品登録の際は表示で登録しています。

もし、対処法をご存じであればご教授ください。
宜しくお願いいたします。

現在の環境
EC-CUBEバージョン 2.0.1
PHPバージョン PHP 5.2.3
DBバージョン PostgreSQL 8.1.4
