Warning: session_start() [function.session-start]:

Jedes mal, wenn ich ein session_start() mache (LOGIN), kommt die Fehlermeldung:
[color=#FF4000][i]
[size=85]Warning: session_start() [function.session-start]: Cannot send session cookie - headers already sent by (output started at /users/solesupplier/www/header.php:22) in /users/solesupplier/www/index.php on line 9

[/i][/color]
