调整屏幕大小时,bootstrap折叠菜单消失

我为我的应用程序使用了bootstrap菜单.它看起来像这样: 菜单好的但当我将窗口大小更改为更小时,它会消失 - 看起来像这样: 菜单消失了它大约约965px时消失(所以可能是979px).我试过这个解决方案,没有用.可能是我正在混合bootstrap 2和3？这是我的菜单代码:

<div class="navbar navbar-inverse navbar-fixed-top">
    <div class="navbar-inner">
        <div class="container">
            <a class="brand" href="/">Digrin</a>
            <div class="nav-collapse collapse">
                <ul class="nav">
                {{ request.path  }}
                    <li{% block nav_stocks %}{% endblock %}><a href="/stocks/">Stocks</a></li>
                    <li{% block nav_mystocks %}{% endblock %}>
                    <a href="/stocks/mystocks">My Portfolio</a></li>
                    <li{% block nav_watchstocks %}{% endblock %}>
                        <a href="/stocks/watchstocks">Watcher</a></li>
                    {% if not user.is_authenticated %}
                    <li class="active"><a href="/accounts/login/?next=/stocks/">Login</a></li>
                    <li><a href="/accounts/register/">Register</a></li>
                    {% else %}
                    <ul class="nav">
                        <li class="dropdown">
                            <a class="dropdown-toggle" data-toggle="dropdown" href="#">

                            </a>
