(PFC1.0-beta11) Undefined index: childs in pfccontainer.clas

[vb]

Everything is working fine.
Chat is great.

In (PFC1.0-beta11) I display number of users in chat
Chat is not activated yet

after

require_once($chatdir .'/src/pfcinfo.class.php');

$info = new pfcInfo($chat_params_serverid);
$users = $info->getOnlineNick(NULL);

I get

8: Undefined index: childs
File:
...phpfreechatsrcpfccontainer.class.php
Line: 661


How to get rid of this.
How to check that chat is not activated.

If chat is running this portion of code gives number of users and I display all users in chat.

Thanks for great work.
