The plugin v3.2 shows an update date of 11/6/2012 but the version number on your site and the version date says 4/6/2012.

Disqus also says there was an update to the Disqus API as of today:
blog.disqus.com/post/35273949228/whats-new-for-the-new-disqus

Is there a different update that I should have gotten?

I also have an issue as outlined here:
forum.joomlaworks.net/disqus-comments-for-joomla-%28package%29/https-content-from-own-site/
I'm hoping that maybe there is an update that would kill all three birds with one stone.....;)
