今天下载了最新版本的FCK，按以前的配置全部配置好了，可是上传图片的时候，浏览服务器会弹出this connector is disabled Please check....这样的错误。终于在网上找到解决办法
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;
}
