default language : impossible to set ?

hello everybody,

I would like to configure FCKeditor (in a php page) default language in english, but it doesn't work :

I put functions js, the same than in the sample 2

$sBasePath = $_SERVER['PHP_SELF'] ;
$sBasePath = ...if i write this line I cannot post the message  :shock:  :?:  :?: 
$oFCKeditor = new FCKeditor('FCKeditor1') ;
$oFCKeditor->BasePath = '/FCKeditor/';
$oFCKeditor->Value = $texteNews;
$oFCKeditor->Width  = '100%' ;
$oFCKeditor->Height = '500' ;
$oFCKeditor->Create() ;

It always put french language. When I change the language, it I tried the sample 2 in the FCKEditor directory, and it works, the autodetect detect french, and when I change the language it works. So I tried to simply copy past all the content of the sample 2 in my test file, just changed $oFCKeditor->BasePath = '/FCKeditor/'; and... it does not work again ! I really don't understand...

Can someone help me ?

Many thanks !
