Hilfe! Wer kann mir weiterhelfen

[centaurus]

Ich habe nach der Installation von CrackerTracker zu Schutz vor Spam usw. folgende Fehlermeldung.

Kann mir vielleicht jemand weiterhelfen, was die bedeutet, was ich jetzt machen soll? Ich kann den Fehler leider nicht finden:

Was bedeutet 'headers already sent'?
