Salve Ragazzi,volevo farvi una domanda.
Ho istallato uno script in phh login e pass.
Sembra tutto andare bene,l'unico problema che riscontro è che quando non inserisco nulla nel campo del form (join _form.php) e clicco su invio mi a questo errore:
Warning: session_start(): Cannot send session cache limiter - headers already sent (output started at /home/xxxxxxxxxxx/domains/xxxxxxxxxxxxxxx.com/public_html/log_in/register.php:25) in /home/xxxxx/domains/xxxxxxxxxxxxxx.com/public_html/log_in/join_form.php on line 2.
Non riesco a capire dove possa essere l'errore.
QUESTO E' IL CONTENUTO DEL FILE REGISTER.PHP
