Answer 1

OK，我们将要看看什么是错的或者是什么原因造成的错误。所以上手加入这行

<customErrors mode="Off"/>

下

<authentication mode="Windows"/>

在你的web.config文件。

然后尝试并加载你的页面，它应该产生一个详细的错误信息，究竟在何处发生了误差，即哪一行代码

Answer 2

检查你的URL（Web服务地址）在你的代码的AJAX部分。

Answer 3

5XX错误是内部错误，通常是与您的代码或在您的服务器缺少一些配置相关联，因为它是一个支付的主机，我想认为这是你的代码有问题，尝试启用详细的错误页面。添加到您的web.config

  <system.web>
    <customErrors mode="Off">
   </system.web>

记住要更改此选项回你完成调试时
