there i would really like some help with the chat option,

hey there

i would really like some help with the chat option, i would like it in bottom corner as well as contact page, i seem to have it show in the bottom corner however when i test from another pc it shows moderator has closed session, i have checked its active and in settings.
how do i add to contact page also, and where from do i answer chat replys, when on site logged in from homepage or do i need to be somewhere else.

also should my view be a basic screen?

sorry really appreciate your time
