我的是托管在 1and1 服务器上的 Asp.Net MVC 4 应用程序。
我将 SimpleMembership 提供程序与 Asp.Net MVC 4 和 codefirst 方法与实体框架一起使用。
一切正常，但我随机收到此错误。
我只在 1and1 主机中收到此错误 - 在任何其他主机中都没有，甚至在我的本地机器中也没有

我正在使用基于角色的安全性（框架 4 中的简单默认设置。）
我检查了数据库，存储过程已经存在。此外，此错误不是每次都弹出，而是随机弹出。
问题：
我错过了什么吗？我需要进一步配置吗？为什么我会收到此错误？为什么是随机的？使用 MVC 4 有什么不同吗？
我在上面搜索了很多，每个人都建议使用 aspnet_regsql 实用程序来注册 db 以进行表单身份验证。我已经检查过了，向导生成的所有内容都在我的数据库中，但我仍然收到此错误。
