Why am i unable to make replies. I've been able to post, but there is no box for reply.
I would suggest doing a hard reset within your browser, while in the forum you wish to reply to. This can easily be done by pressing control and F5 together while on a desktop. For mobile you would have to clear your browsing data and cached images and files within your browser settings. This has helped users with similar issues to yours in the past.
Please let us know if this worked for you, or if you are still having the issue.
