After git pull, all sources is updated correctly. In view of "File tab", I can see the source as following:
<body>
<div class="page-header">
{% if user.is_authenticated %}
<a href="{% url 'post_new' %}" class="top-menu"><span class="glyphicon glyphicon-plus"></span></a>
{% endif %}
<h1><a href="/">DJ's NMU test webpage</a></h1>
</div>
<div class="content container">
<div class="row">
<div class="col-md-8">
{% block content %}
{% endblock %}
</div>
</div>
</div>
</body>
but, after reloading on web tab, this page is seen without all {% %} parts as following:
<body>
<div class="page-header">
<h1><a href="/">DJ's NMU test webpage</a></h1>
</div>
<div class="content container">
<div class="row">
<div class="col-md-8">
</div>
</div>
</div>
</body>
I can see everything on my local server. What happened on it? What does pythonanywhere make difference?
