 * Hi people! I installed WordPress 2.5 in Italian and after that I configurated
   the file wp-config.php. But I have a problem because when I try to open this 
   page [http://www.crismonblog.org/wp-admin/install.php](http://www.crismonblog.org/wp-admin/install.php)
   there is an error, i.e. Fatal error: Call to undefined function untrailingslashit()
   in /var/www/vhosts/crismonblog.org/httpdocs/wp-includes/functions.php on line
   241. Does anybody know the reason why it happens? What am I supposed to do?
    
   thank you very much guys for your help!
