Ajaxを使用してフェッチされ、jQueryオーバーレイで表示されるログインフォームに関する問題を解決しています。オーバーレイは完全に機能しますが、問題があるのは、submit（誤った詳細を使用）をクリックすると、適切なエラーを表示する代わりにオーバーレイが閉じられることです。 PHPコードはログインページ（admin/index.php）にあります。ログインフォーム>フォームエラーでオーバーレイが発生する
ボタンのHTML：
<input name="Submit" type="submit" value="Log In" class="submit" />
FORMタグのHTML：
<form id="loginForm" method="post" action="">
