advanced guestbook problem !! plz help ...

I get this mistake, when send the commentary and there is mistake of the formatting the page.

Warning: Cannot modify header information - headers already sent by
(output started at c:\appserv\www\eshop\includes\classes\boxes.php:69)
in c:\appserv\www\eshop\includes\classes_gb\comment.class.php on line 176

What reason of this defect? However, commentary is written orderly in the guestbook...

my advanced guestbook is verson 2.3.1

Could be any one of a number of things.

I'm guessing you've made changes to the script and somewhere there's an error - could be something really trivial such as an extra space.

Do a search, there's been loads of questions about this and carefully check any changes you've made.

If you still can't resolve it please post the URL of your guestbook.

Thats the error you get when trying to edit the folders via the admin section of the guestbook. And you dont have your chmod settings set correctly. Better to edit them via your ftp client or your cpanel file manager.

The problem seems to me that you are using the guestbook in a CMS and the CMS is sending out information before it sends the guestbook so when they guestbook tries to write a cookie it fails because a cookie has to be sent before everything else.
