The code processes the _POST variable and since Zikula has changed how the variables are processed I am not sure this is why the problem has appeared. The IPN function is the following http://agilityjot.com/index.php?module=UpgradeUser&func=paypalIPN and the function in the following:
Code
function UpgradeUser_user_paypalIPN()
{
$dbconn =& pnDBGetConn(true);
$pntable =& pnDBGetTables();
// This is for checking PDT (payment data transfer)
// read the post from PayPal system and add 'cmd'
$req = 'cmd=_notify-validate';
foreach ($_POST as $key => $value) {
$value = urlencode(stripslashes($value));
$req .= "&$key=$value";
}
// post back to PayPal system to validate
$header .= "POST /cgi-bin/webscr HTTP/1.0\r\n";
$header .= "Content-Type: application/x-www-form-urlencoded\r\n";
$header .= "Content-Length: " . strlen($req) . "\r\n\r\n";
// $fp = fsockopen ('www.paypal.com', 80, $errno, $errstr, 30);

Because I am reading the _POST from within this function I am not sure this is what is causing the problem or if it is something from Paypal but since this problem has only occurred since I have upgraded it does seem suspect. The payment is accepted but it continues to send the function and send the confirmation email but it does not continue to take payment (unfortunately
) -- So I am not sure if I need to change this function ... any help is much appreciated!!
