the code for all of the gateways and all of the shipping service providers needs to be in the confirm page, it is only used though, if you enable them in the store settings.
It looks like the success redirect is not getting set for some reason.
try changing:
<?php
if ((isset($_POST["Submit_order"]))) {
//WA Universal Email object="mail"
//Send Loop Once Per Entry
$RecipientEmail = "".((isset($_POST["email"]))?$_POST["email"]:"") ."";include("WA_Universal_Email/WAUE_confirm_1.php");
unset($_SESSION['WA_ECart_Coupons']);
//Send Mail All Entries
if (""!="") {
header("Location: ");
}
}
?>
to:
<?php
if ((isset($_POST["Submit_order"]))) {
//WA Universal Email object="mail"
//Send Loop Once Per Entry
$RecipientEmail = "".((isset($_POST["email"]))?$_POST["email"]:"") ."";include("WA_Universal_Email/WAUE_confirm_1.php");
unset($_SESSION['WA_ECart_Coupons']);
//Send Mail All Entries
if ("checkout_success.php"!="") {
header("Location: checkout_success.php");
}
}
?>
