FluxCP-rA PayPal Problem

[Feistz]

Hello rAthena,

I have a problem with my fluxcp paypal feature. Whenever I made a donation, it will not add Donation credit to my account. I already setup the PayPal IPN link and I use PayPal Sandbox site.

Here is my paypal.log.php

Btw, I'm using Xantara FluxCP-rA.

Can anyone help me on this?
