解决办法:

打开editor/filemanager/connectors/aspx/config.ascx

修改CheckAuthentication()方法,返回true

private bool CheckAuthentication() {   // WARNING : DO NOT simply return "true". By doing so, you are allowing   // "anyone" to upload and list the files in your server. You must implement   // some kind of session validation here. Even something very simple as...   //   //  return ( Session[ "IsAuthorized" ] != null && (bool)Session[ "IsAuthorized" ] == true );   //   // ... where Session[ "IsAuthorized" ] is set to "true" as soon as the   // user logs in your system.

  return true; }

挺好用的
