Frågor om kodning till min hemsida!

Hejsan !

Jag vet att jag skapat många trådar nu så jag skapar en tråd istället nu med mina frågor ang min hemsida som jag gygger på just nu.

Jag har fått fart på min chat nu då men fortfarande har jag lite ? om det.

I chat fönstret dit man skickar sitt medelande så långst upp i det kommer dessa felmedelanden upp varför:

Warning: Cannot modify header information - headers already sent by (output started at /home/test/chat/shout.php:2) in /home/forcevis/public_html/test/chat/shout.php on line 141

Warning: Cannot modify header information - headers already sent by (output started at /home/test/chat/shout.php:2) in /home/forcevis/public_html/test/chat/shout.php on line 142

Warning: Cannot modify header information - headers already sent by (output started at /home/test/chat/shout.php:2) in /home/forcevis/public_html/test/chat/shout.php on line 143

Warning: Cannot modify header information - headers already sent by (output started at /home/test/chat/shout.php:2) in /home/test/chat/shout.php on line 144

Det roliga med detta är att detta kom efter ett tag som jag prov kört chatten alltså inte direkt. vad kan felet vara med detta?
Raderna den klagar på är dessa:

header('Cache-control: private, no-cache, must-revalidate');
    header('Expires: Sat, 01 Jan 2000 00:00:00 GMT');
    header('Date: Sat, 01 Jan 2000 00:00:00 GMT');

Nope det finns det inte ser ut som följande:

Men detta blev efter ett tag alltså inte från början när jag test körde den.

jag vet inte.
Du kan få hela kodningen för sidan :

Så ser den ut massa skit men se om ni kan hitta varför det felmedelandet kommer fram. Väldigt tacksam om ni hittar det !

Menar du om jag har enter slag efter

<?
error_reporti

menar du ?

Rosenson det verkade fungera när jag tog bort mellan rum. Tackar för hjälpen !
Jag undrar nu i chaten så sparas ju inläggen man skrivit. Kan man göra så att inläggen raderas efter ett visst antal timmar?
Lägger man det i mysql databasen eller lägger man det i någon av php filerna ?
