我正在使用Oscommerce v2.3.3.4并使用PayPal网站付款标准模块设置超过一年。它工作正常，直到上个月我收到了很多具有相同标题的电子邮件：PayPal IPN Invalid Process提到standard_ipn.php失败。以下是代码：

我已经通过IPN模拟器测试过，但没有发现任何错误，但仍然收到错误电子邮件。有人请帮忙。
答案 0 :(得分：0)
找到行
if ( ($res == 'VERIFIED') || ($res == 'INVALID') ) {
$result = $res;
break;
}
并将其替换为
if (strstr($res,'VERIFIED')) {
$result = 'VERIFIED';
break;
}
