Made some tweaks to the ajax login javascript. Cleared the inputs on failure so someone won't repeatedly try a bad login. Redirect on lockout so the page will refresh. Set focus on the username box after failure for convenience.

{% load url from future %}
{% if show_button %}
<a href="{% url 'forums-edit_post' id=post.id %}"><img src="{{ STATIC_URL }}icons/page_edit.png" alt="Edit post" title="Edit post" /></a>
{% endif %}
