So my visitors have told me, and also I noticed a couple of times, that sometimes, when trying to get to my site (http://thethirdbar.com/) people are asked for a password. After a few more attempts they ususally can reach the site but it’s annoying still.
Have you resolved this issue yet? If not can you provide any more deatils like whether or not the visitors who are experiencing it when they are already logged into wordpress.com? if they are already logged in then this ought not to be happening. If they aren’t then they will need to log into wordpress.com in order to leave comments.
