Inability to reply to or post comments Answered
I am running Chrome Version 24.0.1312.57 on Mac OS X Lion 10.7.5., and have tried this out on Safari too, without any difference. I just received a new comment on my post, and went to say thank you - however, when I typed the captcha and my message, it still gave me the 'Please type the two words as seen in the image' message. I also noticed that a comment that I thought I had already replied to doesn't have my response to it, and I can't see how to reply to it at all. If you check out the screencap, you'll see what I mean.
Hope that's enough to get you an idea of my situation,
