The picture clearly shows that there is one comment, but it isn't visible. Clicking on the "Reply" button doesn't seem to work either.

Hi Sreejato that is a known minor bug. What happened was someone commented on your solution and then deleted their own comment. The comment goes away, but the reply counter does not go down.

Is this preventing your from commenting on your own solution?

Oh, thanks for replying. I was curious to know what the comment said.

And no, that isn't preventing me from commenting on the solution. :)

Well I won't give details for privacy reasons, but basically someone asked a question about the techniques used in your solution and then felt self-conscious about whether or not it was a good question and then deleted it. Happens all the time, sometimes people delete their own comments for good reasons(e.g. they realize it was a poorly formed statement, question etc...) and sometimes people delete them for bad reasons.

Thanks for reporting it, and nice design work to obscure your solution. That is a particularly warm red. We will take steps to fix it.

I checked it. The same bug occurred. Before also.
