My forum has been hacked!

[MGT_STC007]

Can anyone help me restore this?

When you pull that link up you can see a list of errors.  When I goto those pages listed the only thing in them is the words "hacking attempt....."

Actually it's coming up on every page in the main forum source folder.

What can I do?

Apply the PHP 4.4.0 Compatibility Patch.

That's it!  All I did was replace the one file and it's fixed!  Anything else I need to do?  Thanks so much!!!!!!
