Comments get re-directed to Feedblitz?

When anyone tries to leave a comment on my site, they currently get re-directed to feedblitz??? I’m using both feedblitz and feedburner and neither seem to have any problems on their end. I’ve looked at the plug-ins and the privacy options and can’t see anything obvious? I’m just going to update to the very latest WP and see if that helps, but in the meantime any ideas?
