总是显示Invalid Request
在fckconfig.js中找到FCKConfig.LinkBrowseURL将其后面改为：
FCKConfig.LinkBrowserURL = FCKConfig.BasePath + 'filemanager/browser/default/browser.html?Type=File&Connector=' + encodeURIComponent( FCKConfig.BasePath + 'filemanager/connectors/' + _FileBrowserLanguage + '/connector.' + _FileBrowserExtension ) ;
即增加了"?Type=File",同样，找到FCKConfig.LinkUploadURL修改为
FCKConfig.LinkUploadURL = FCKConfig.BasePath + 'filemanager/connectors/' + _QuickUploadLanguage + '/upload.'
+ _QuickUploadExtension+'?Type=File' ;
如此即可解决此问题！
