Comment Problems

Hello folks, I have searched several of the threads trying to find an answer to this problem but have not found an answer that fits. My problem is this:

I get the following error when posting a comment:

Although this error is there after every comment, the comment IS posted. I just have to manually go back to the guestbook to view the entry (meaning it does not forward me back automatically). Due to my recent attacks on my board, I have passworded this feature so that only I am allowed to use it.

Does anyone have any clue how to fix this? Thanks in advance.

At a guess you have used includes in your comment.php so the HTML has started befoer it gets to the guestbook script.
