Ajax image upload-form zurück forbidden 403-Fehler

HALLO alle,

Ich bin derzeit am basteln mit dieser pre-Autor ajax/php Bild-Upload-Skript, aber nach fast 2 Tage versucht herauszufinden, warum es wirft 403 forbidden Fehler(Sie haben keine Berechtigung zum access /ajaxupload.php
auf diesem server), ich bin out-of-Optionen, sondern um Fragen an die gurus hier.

Ich vermute, es hat etwas zu tun mit meiner hosts-server-Einstellungen, aber bevor ich ärger Ihnen(dauert ein Tag in der Regel für Sie, um wieder mit Antworten), ich dachte, ich könnte überprüfen mit Euch, im Falle dass mir etwas fehlt, weil ich bin neu mit ajax, und ich vermute, dass dies ist, wo das Skript zu einem Fehler.

Vielen Dank, wer kann vorschlagen, was ich falsch mache.

Prost, Lea.
