Boas Pessoal eu tenho o seguinte código:
login.htm
e depois tenho esse para efectuar o login:
loginin.php
o que se passa é o seguinte, ele não consegue criar as sessões e dame sempre o seguinte erro:
"user existe
Warning: session_start(): Cannot send session cookie - headers already sent by (output started at /home/www/bitzero.freehostia.com/forum2/loginin.php:3) in /home/www/bitzero.freehostia.com/forum2/loginin.php on line 9
