Hi Lord235,
I removed the +o mode and now the /whois NickServ is the same than yours
* [NickServ] (
services@services.XXX.fr): Nickname Registration Service
* [NickServ] is using modes +ioqS
* [NickServ] is connecting from *@services.XXX.fr
* [NickServ] !@#services
* [NickServ] services.XXX.fr :Services du réseau irc.XXX.fr
* [NickServ] is an IRC Operator
* [NickServ] is a Network Service
* [NickServ] Fin de la liste WHOIS.
But the problem is the same, any command tried, always the same message "Unknow command" for any service of Anope, it's really strange
