I am looking into a fix for that. Sadly Google searches are only giving me outdated information, so I have to wait for Disqus support to respond.
Disqus does have an export feature, so if we do switch back, hopefully I can snag all the comments. If you write something huge that you don't want to lose in comments, please keep a backup just in case.
Anyway, back to testing! Hopefully all these bugs will be fixed, and we can move forward with a much better comment system.
One more thing: It looks like the front page comment tallies are actually being overridden. They show up correct to start, then a half a second later are replaced with the incorrect number. I think this may be something in blogger that needs to be axed. I've emailed support about that, hopefully they can nail it for me.
One more note: The Disqus button above the comment box has your settings in it. Some take a few minutes to update. You can also go to the actual Disqus website and edit your settings there.
