FCKEditor 2.6 not using php connector

Hello all,

My problem is that FCKEditor doesn't want to use PHP connectors.
I've modified fckconfig.js like that :

var _FileBrowserLanguage   = 'php' ;   // asp | aspx | cfm | lasso | perl | php | py
var _QuickUploadLanguage   = 'php' ;   // asp | aspx | cfm | lasso | perl | php | py
var _FileBrowserExtension = _FileBrowserLanguage == 'perl' ? 'cgi' : _FileBrowserLanguage ;
var _QuickUploadExtension = _QuickUploadLanguage == 'perl' ? 'cgi' : _QuickUploadLanguage ;

FCKConfig.ImageBrowserURL = FCKConfig.BasePath + 'filemanager/browser/default/browser.html?Type=Image&Connector=' + encodeURIComponent( FCKConfig.BasePath + 'filemanager/connectors/' + _FileBrowserLanguage + '/connector.' + _FileBrowserExtension ) ;

But when I display GetUrlParam('Connector') in browser.html file it's always :
connectors/aspx/connector.aspx

My browser cache is empty, so I don't understand what's the problem.
Thanks for you answer
