Does this mean my forums were hacked?

How come it says a guest is viewing the site owner forums on my forums?! The permissions are in order for site owners only. This is not possible! When I looked up their IP, I did see they were a spammer. Is this person a hacker?

Doesn't mean they are a hack. Guest can and only will be able to see what you want them to see.

Does the IP match up to another admin? Sometimes this can be a way. System might not of updated and its just showing like this.

I wouldn't worry.

It is not anybody in my forums that has the IP. Should I PM it to you? Sites on Google say it is a comment spammer's IP.

Hello,

Some guests might only be a 'spider bot' so they can access some hidden forums, this also happens sometimes on my test forum, but normal guests/people won't be able to see hidden forums unless you permit the guests to see the forums.

Also, if they can't see any forums then they will only see the message:

This board has no forums

They will still appear on the "Who is Online ?" list, however, as a guest. As long you have the correct permissions set, you have nothing to worry about.
