i have installed ejabberd on debian linux, which is working pretty fine,
now it seems that send_message groupchat is gone ..
0 root@xxxxxxxx:xxxxxxx# /usr/sbin/ejabberdctl status
The node ejabberd@localhost is started with status: started
ejabberd 17.04.176 is running in that node
0 root@xxxxxxxx:xxxxxxx# /usr/sbin/ejabberdctl send_message groupchat
{error,unknown_command}did i miss something, or does anybody have a clue ?!
