Thread:Extension talk:ConfirmEdit/Sorry but in locale (xampp, vista) confirmEdit doesn't show anything

Hi, I am not very good at PHP but I did what is explained to install confirmEdit, for example adding:

into mediawiki/LocalSettings.php

I get no php error when I edit a page, but I don't see anything, nothing is asked to confirm Editing... I tried to add  at the end of ConfirmEdit.php and it is executed, I can see it when I did a page.

I tried mediaWiki 1.20 and the corresponding confirmEdit, then I tried mediaWiki 1.19 and the corresponding confirmEdit. Each time, I tried every $wgCaptchaClass possible, and it never worked. So what is the problem my friends ? My mediawiki works perfectly, I don't have any cache activated or even installed on my xampp. This is my config :

I you have an idea, could you please notice me at acx01b@yahoo.fr, Thank you very much !
