Suspicious users

Hi,

I don`t know that is happening but I belive my forum is attack by hacers.
One topic of my forum is split on 2 different topics, and one of them is locked. I removed special users (moderators), unlock the topic, try to put it back 2 topics in 1, and coundn`t.
Everytime I try It says one topic is locked, and I know I unlocked it 2 seconds ago.
When I go in admin panel I see many users from Virginia and California, I banned the adresses, but I don`t know where they coming from, but few seconds ago I see they are on forum again.
Also I see in last post of one topic sending links from other topics from my forum, and the user are coming from is not online. I banned it anyway, and I see link again. How is that possible????
Also now, I delete message from the user I banned, and the spamming link is shown on the other users post which is the last at that topis (locked topic), I didn`t locked I really don`t know what`s going on?
And how can I do backup for forum??

Tnx

Um very very very difficult to understand what you are saying.

ACP < Users and Groups < Administrators < Delete everyone except yourself from the group < Save

Index < Profile < Change your password < Save

ACP < Generals < Forum On Holiday: Yes < Save

ACP < Generals < Forum Underconstruction: Yes < Save

Put it in defensive mode like that and while the forum's on construction, fix the things you need fixing.

Thanks. If it`s automaticly split the messeges into 2 topic, no worries about it.
Can u tell me how to change the titile of topic? I`m trying to find...
Also, as u can see on this pic, the links are shown by their own, no one doesen`t post it. Is it spamming?
How they show there? Btw that`s the last page of locked topic, and the links are from the previous pages. I delete those links once, but shown again.

for changing the name of topic that's easy all you have too do is hit the edit button and then send... same goes to links or text highlight then (Del) make sure you click the send button

Thank u iyaaz for explaning how to change title of topic, so easy, shame to not found it myself
For link that`s shown, I already deleted once but was shown again, first one link, after a while another... I deleted now again, but I`m sure it will shown again...

Are those links connected to the topic that was split?

No, they are from the same topic where they shown, only previous pages...

Can guests see these topics? If they can, please post the links to those two topics.

Please change the title of your topic, that is related to your question/issue, so that other users will be able to find their question/issue using the search engine.

If not, please do change the permissions by following these steps:

ACP < Generals < Categories and Forums < Forum of the one with the said permission < Permission < Set it in guests, but make sure you're careful on where to set it as guests in the forum's permission < Save

Edit: The said steps is the way for you to allow guests to view it in case you didn't get what I said.

Since the last time I deleted It`s not show again.
You can lock the topic.
