未显示编码器注册选项卡

我使用codeigniter与基础作为我的前端，在我的索引视图上，我有一个与登录和注册表单的选项卡，我的登录表单选项卡显示，但当我点击注册选项卡时，它不显示。当我查看页面源时，注册视图已经正确加载到我的主视图中，它只是不显示。

authentication.php(默认加载的视图)

<div class="row">
    <div class="medium-12 columns">
<ul class="tabs" data-tabs id="authentication_tab">

</ul>
<div class="tabs-content" data-tabs-content="authentication_tab">
