我的用户控件属性中出现以下错误：
Error reading usercontrols/BrandHub/emintRegister.ascx
The following list shows the Public Properties from the Control. By checking the Properties and click the "Save Properties" button at the bottom, umbraco will create the corresponding Macro Elements.

我试过“/usercontrols/BrandHub/emintRegister.ascx”，但我得到了同样的错误。
网页上显示以下错误消息：
Error creating control (/usercontrols/BrandHub/emintRegister.ascx).
Maybe file doesn't exists or the usercontrol has a cache directive, which is not allowed! See the tracestack for more information!
有人能帮忙吗？
