Cannot ass header error...

I keep getting this error:

Warning: Cannot add header information - headers already sent by (output started at C:\Inetpub\wwwroot\start.php:7) in C:\Inetpub\wwwroot\admin\functions.php on line 1490

any ideas on how to troubleshoot it?

Thanks

What's start.php? For some reason you echo (or send other kinds of headers) in line 7 of it.

its my main page(non-vb), i have a log in part on there that seems to cause this error.

are you trying to set cookies?
if so they have to be sent before any output, this includes whitespace and text.

Do you have an echo, print or even ?> html here <? on line 7 you will have to relocate it to above the part where content is being sent to the browser.

Move this bit:

<?PHP
chdir("");
require("/global.php");
error_reporting(7);
//connect to database

mysql_connect("localhost", "AllAboutSpeed", "aasfast");
mysql_select_db("aas");
$usernum = mysql_query("Select count(*) from user");
$users = mysql_fetch_array($usernum);
?>

to the very top of the file, before <html>.
