Thank you all for your suggestions. Unfortunately I have already tried this, and it doesn't work for me (I am running PHP: 5.1.6). I have only tested this on my own PC, but if it doesn't work here, I would be very surprised if it would work on the remote server. Index.php starts: <?php //;V;;; Cypalda/Index.php Printed: session_start (); setcookie (); setcookie ('user_id', 'Wilma*Witgenstein', time()+3600); And this produces the following output: Warning: setcookie() expects at least 1 parameter, 0 given in D:\Websites\cypalda.com\index.php on line 4 Warning: Cannot modify header information - headers already sent by (output started at D:\Websites\cypalda.com\index.php:4) in D:\Websites\cypalda.com\index.php on line 5 It is interesting to note that the second diagnostic is generated because the first diagnostic is taken to have initiated the headers. I think I can live with this limitation, but this diagnostic is a warning of the hassles I am likely to face if I cannot find a way around it.
