Hello people,

I've been developing this little extranet thing on my mac and now that 
it seems ready to fly I uploaded it onto my web server but now I get 
these 2 errors:

Warning: Cannot send session cache limiter - headers already sent 
(output started at /var/www/xtranet-staging/upload.php:1) in 
/var/www/xtranet-staging/upload.php on line 3

Warning: Cannot add header information - headers already sent by 
(output started at /var/www/xtranet-staging/upload.php:1) in 
/var/www/xtranet-staging/upload.php on line 91

Basically I know why I get these warnings, ie: I'm sending headers 
twice (the second warning is caused by the 
header("location:upload.php") function call). What I don't get is why 
are headers being sent without my knowledge? This works fine just 
running off my home computer so what's the deal? Is there something in 
the php.ini file that I need to enable or disable?

Thanks, as always, for your help.

Greg
