他の投稿からわかることは、データベースへの接続文字列に問題があるということです。ただし、提供された接続文字列を AppHarbor からコピーして、web.config に入れました。

これまで、自分のアプリを localhost でしか実行したことがなく、すべてが常に正常に実行されていました。誰かアドバイスをお願いできますか？

結局のところ、両方のアプリケーション接続文字列に新しい SQL サーバー接続文字列を含めていませんでした。私のアプリケーションのほとんどはカスタムメイドの接続文字列を使用していますが、DefaultConnection はログイン ページと登録ページに使用されていました。

提供された接続文字列を DefaultConnection に追加すると、すべて正常に機能しました。
