Problem :
quick upload files is not working( show error window - Invalid Request ), upload in resource browser working
quick upload images and flash files is working.

My configs :
fckconfig.js :

FCKConfig.LinkBrowser = true;
//default not working
//FCKConfig.LinkBrowserURL = FCKConfig.BasePath + 'filemanager/browser/default/browser.html?Connector=' + encodeURIComponent(FCKConfig.BasePath + 'filemanager/connectors/' + _FileBrowserLanguage + '/connector.' + _FileBrowserExtension);
//mycorrect not working
FCKConfig.LinkBrowserURL = FCKConfig.BasePath + 'filemanager/browser/default/browser.html?Type=File&Connector=' + encodeURIComponent(FCKConfig.BasePath + 'filemanager/connectors/' + _FileBrowserLanguage + '/connector.' + _FileBrowserExtension);

// default not working
//FCKConfig.LinkUploadURL = FCKConfig.BasePath + 'filemanager/connectors/' + _QuickUploadLanguage + '/upload.' + _QuickUploadExtension;
//mycorrect not working
FCKConfig.LinkUploadURL = FCKConfig.BasePath + 'filemanager/connectors/' + _QuickUploadLanguage + '/upload.' + _QuickUploadExtension + '?Type=File';

Config.ascx

// URL path to user files.
UserFilesPath = "~/userfiles/";

// The connector tries to resolve the above UserFilesPath automatically.
// Use the following setting it you prefer to explicitely specify the
// absolute path. Examples: 'C:\\MySite\\userfiles\\' or '/root/mysite/userfiles/'.
// Attention: The above 'UserFilesPath' URL must point to the same directory.
UserFilesAbsolutePath = "D:\\web\\simple_site\\userfiles\\";

...

TypeConfig[ "File" ].AllowedExtensions = new string[] { "7z", "aiff", "asf", "avi", "bmp", "csv", "doc", "fla", "flv", "gif", "gz", "gzip", "jpeg", "jpg", "mid", "mov", "mp3", "mp4", "mpc", "mpeg", "mpg", "ods", "odt", "pdf", "png", "ppt", "pxd", "qt", "ram", "rar", "rm", "rmi", "rmvb", "rtf", "sdc", "sitd", "swf", "sxc", "sxw", "tar", "tgz", "tif", "tiff", "txt", "vsd", "wav", "wma", "wmv", "xls", "xml", "zip" };

TypeConfig[ "File" ].FilesPath = "%UserFilesPath%file/";
TypeConfig[ "File" ].FilesAbsolutePath = ( UserFilesAbsolutePath == "" ? "" : "%UserFilesAbsolutePath%file/" );
//correct all quick path add %file
TypeConfig["File"].QuickUploadPath = "%UserFilesPath%file/";
TypeConfig["File"].QuickUploadAbsolutePath = (UserFilesAbsolutePath == "" ? "" : "%UserFilesAbsolutePath%file/");
