Voici le code dans config.php :

#http://wiki.cmsmadesimple.org/index.php/FAQ/Installation/Pretty_URLs#Pretty_URL.27s
$config['url_rewriting'] = 'mod_rewrite';

#Extension to use if you're using mod_rewrite for pretty URLs.
$config['page_extension'] = '.html';

#If using none of the above options, what should we be using for the query string
#variable? (ex. http://www.mysite.com/index.php?page=somecontent)
$config['query_var'] = 'page';

j ai corrigé le code .htaccess et essayé la solution alternative que tu as donné.
Rien à faire: les url changent mais elles ne sont plus accessibles
