Go to your admin page and tuirn everything off that you do not want on. Is it possible someone had your login info? It's odd that this happened while you were on vacation.
Who knew you were on vacation and might have had your login info?
If it were more than just you, it might have been a server glitch, but no one else has complained about this. I don't think N54 would bother to go in and change your forum settings. It is not normally the way they do things. If there was a problem on your forum that required their intervention, they would simply shut it down.
That being said, what's all the fuss about IP addresses?
