I have installed many magento sites but this time I am facing something unusual : the custom options available at the end of my simple product definition is there, but when I clic on it, nothing happens (page remains the same after a short reload). If I force to open it in a new tab (FF 3) I can see the given picture. (I have french language on my site). If I clic on the button nothing happens. (Same pb with IE8).
(PS : I am using 220.127.116.11 version. Same pb on 18.104.22.168 but not on 22.214.171.124...)
