express form の複数のHTMLインプットから画像がポストできない
写真を撮って応募してもらうサイトを作っています。
ゲストにexpress form のHTMLインプットから4点の画像を必須で投稿させたいのと、応募されたポストを閲覧できるようにエクスプレスエンティティを使用しています。
以前は（Version - 8.4.0だったと思います）上記の条件をクリアしポストしていたのですが、現状、2Mほどの写真を1点くらいしか送れません。
必須にすると「写真２は必須です」のようなエラーが出てポストできません。
めぼしいエラーログは出現せずどこを見ていけばいいのかわかりません。
バージョンを落として再インストールした方がいいでしょうか？
※アップデートを境にというよりはパッケージの「confirm_express_form_pack」というものをインストールした後に起こったように思います。定かではないですが。
