Does this only happen on your Opinions or are you unable to reply to any Opinions? What happens when you try to reply? Does the text box not appear at all or does it not submit after you type your reply? If you can't respond to my Opinions here, you can send me a message. Also let us know what device and browser you're using.
You should always have that option.. there is a reply back to to all senders of a comment on every opinion.. but if you cannot send one back he may have you blocked that is the only way you can send nothing to this person.. other then that you should be able to.. if not then ask a moderator why.. take care now
Well, if you are unable to reply or if the reply button is not working then the only possibility is that the person has blocked you. However it's not possible that everyone has blocked you, because you say it's not working anywhere then probably there is some technical issue with your account.
