I am sorry for the late reply.
Strangely we can't replicate this issues regarding cannot enter forum.
And about komento, you didn't have any comments on the blogpost; that why it doesn't show anything. I commented on this blogpost and here the screenshot: http://screencast.com/t/FnmQFu6bRP .
Strange, I cannot replicate the same issue from your site. Please see http://screencast.com/t/k3s9VwJKFtr
Can this be same issue earlier on with your web browser cookies issue? Try to clear your web browser the cache and the cookies and see if that help or not.
Please advise.
