Jimmy: Put ob_start(); at the very beginning of your index.php, just after the <?php

IE:
PHP Code:
<?
ob_start();

and put ob_flush(); at the end of your page..

also, check and see if you are creating any other html before you start your php code, that can cause it too

And what does this actually do.
I have had some problems [Warning:] setting a cookie until I add these functions.

PHP Code:
<?
ob_start();
                 // Site
ob_flush(); 
?>

this is directly from php.net:

http://www.php.net/manual/en/function.ob-start.php

ob_start(); : This function will turn output buffering on. While output buffering is active no output is sent from the script (other than headers), instead the output is stored in an internal buffer.

The contents of this internal buffer may be copied into a string variable using ob_get_contents(). To output what is stored in the internal buffer, use ob_end_flush(). Alternatively, ob_end_clean() will silently discard the buffer contents.

ob_flush(); :

http://www.php.net/manual/en/function.ob-flush.php

This function will send the contents of the output buffer (if any). If you want to further process the buffer's contents you have to call ob_get_contents() before ob_flush() as the buffer contents are discarded after ob_flush() is called.



basically ob_start stores the output information, ob_flush then sends it to the browser..
