Some users are still having problems with the pop-up login. I think they are actually getting 403s because of the CSRF protection. So I have modified the base template to always have a javascript variable called csrf_token available when they aren't logged in. The ajax_login.js script was then modified to send this value with the ajax post. Fingers crossed.

{% extends 'base.html' %}
{% load url from future %}
{% block title %}Shout Not Found{% endblock %}
{% block content %}
<div class="breadcrumbs"><a href="{% url 'shoutbox-history' %}">Shoutbox History</a> &raquo; Shout Not Found</div>
<h2>Shout Not Found</h2>
<p>We're sorry, it looks like that shout no longer exists.</p>
{% endblock %}
