Header errors with an include

pisang

I'm extremely noobish so forgive my ignorance, but I got the following thing.

I got an index.php file with 3 includes,

<?
include("top.php");
include("index_f.php");
include("bottom.php");
?>

Where index_f is the phpBB (a well known piece of forum software) index file.

But, when loading up the index.php, I get the following error:

Warning: Cannot add header information - headers already sent by (output started at /home/sites/site29/web/forum/top.php:11) in /forum/includes/page_header.php on line 449

I figured it means the top.php already send the HTML headers, yet, there aren't any in top.php (php creating a picture).

Thanks in advance

Ok, what this means is that the PHPBB tried to send headers to the user, most likely trying to set a cookie, but the problem is cookies can't be set if you've already sent any output to the user, which your top.php probably did. So unfortunately you won't be able to add other code to the PHPBB page like this, but there must be an option within PHPBB to add aditional HTML code above and below the message board. Check the documentation.
