Xabber -XMPP Web Client

Xabber - XMPP Web Client

I am in need of a developer who have a complete knowledge of XMPP web client called Xabber.

I already have a xabber - xmpp client which is run on my website already . I just need only one thing to do is. After close web client the history of chat is not loading. I just need History of chat.

CHAT HISTORY

And no other things.

Thanks
