客户网站出现异常错误

Question

我刚刚在我客户的网站上创建了一个帐户（我为他建立的）。我已经对这个网站进行了广泛的测试，但没有发现任何问题 - 2 年前。自从网站发布以来，我已经对其进行了测试，以确保它每个月都能顺利运行。

我刚刚在他的网站上创建了一个新帐户，我收到了这个错误：

Server Error in '/' Application.

什么？？？下面列出的电子邮件地址是我用来创建帐户的电子邮件地址。收到此错误后，我使用我的所有邮件在线登录该电子邮件帐户 - 它就在那里。所以用户确实存在。那么，为什么在尝试向其发送电子邮件确认时，WebPages 框架会认为该用户不存在？

您在代码中看到的电子邮件变量 - 它的值列​​在异常本身中。

Answer 1

由于某些原因，邮箱可能在几分之一秒内不可用。再次尝试创建帐户，应该没问题。
