Problem mit "Headers already sent by"

[lukiono]

N'Abend

Ich habe ein neues Forum installiert und der Webspace hat 2 Url's:
utm-rl.com
utm-rl.net

Das Problem ist komisch. Bei der .net Domain taucht die Meldung nicht auf, hingegen bei der .com schon:

Code: Alles auswählen

[phpBB Debug] PHP Notice: in file /index.php on line 86: date() [function.date]: It is not safe to rely on the system's timezone settings. You are *required* to use the date.timezone setting or the date_default_timezone_set() function. In case you used any of those methods and you are still getting this warning, you most likely misspelled the timezone identifier. We selected 'Europe/Berlin' for 'CEST/2.0/DST' instead

Über Google und die Boardsuche habe ich nichts konkretes gefunden.
An was liegt das?

Edit: Beim Abschluss der Installation kam diese Fehlermeldung auch und nach dem aktualisieren: "Schwerer Installationsfehler"

Kind regards

Das wage ich zu bezweifeln:
search.php?keywords=headers+already+sen ... bmit=Suche

Man sollte dann auch mal auf das eine oder andere Suchergebnis klicken, dann findet man z.B. https://www.phpbb.de/kb/headers_already_sent
