I think I found what the problem is. I could not reply to topics even when I logged in as administrator. I cleared the cache (in FireFox and Chrome) and then the message “You must be logged in to reply to this topic” disappeared and everything went back to normal.
This is rather confusing – what can be done so that it doesn’t happen again?
Has anyone come across this issue?
Thanks.
