403 access denied for my-chat-status path, chat bar doesn't show online users, can't change status but chat is working

Hi,

I can chat with other users if, and only if, i click at the name of the block listing online chat users. Only this way a chat window is opened.

Unfortunately i found 3 bugs that are critical:
1- When i try to access http://example.com/my-chat-status i get a Access Denied.
2- Chat bar never shows online users (always 0), but blocks and views show them correctly.
3- I can't change my status to invisible, busy or even offline.

So...is this module still active?

Any help about how to solve it?

Thanks
