I installed chat plugin and opened a chatroom here
As far as I was logged in as admin user everything was ok, but when I logged out to try Twitter and Facebook login options I realized the whole page (and not the chat frame only) refreshes at the given interval.
I’m using a twitter-bootstrap-based framework, if this helps.
Please, be also advised that
class="row" which is used by plugin developer conflicts with framework standard rules and the message div is partly hidden as it takes a
margin-left:-30px declaration usually assigned to “row” class.
