オンラインでテーマを購入しましたが、新しいテーマの代わりに古いjquerymobileを使用していると思います。
現在、私のヘッダーでは次のようになっています。

最新のjquerymobileにアップグレードするために、これらの行を頭の下部に追加しようとしましたが、IIが何かを台無しにしたため、ボタンが2つになりました。それはcssが本当にはげしいものを台無しにしたようでした：
<link rel="stylesheet" href="http://code.jquery.com/mobile/1.2.0/jquery.mobile-1.2.0.min.css" />
<script src="http://code.jquery.com/jquery-1.8.2.min.js"></script>
<script src="http://code.jquery.com/mobile/1.2.0/jquery.mobile-1.2.0.min.js"></script>
