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 forum_tags %}
{% block title %}Forums: New Topic{% endblock %}
{% block custom_js %}{{ form.media }}{% endblock %}
{% block content %}
{% forum_navigation forum "New Topic" %}

{% show_form "New Topic" form "Submit" 0 %}
{% endblock %}
