Hi, At the beginning of the jomsocial installation, you ask for a special configuration on the site hosting for the private message plugin to work but I don't remember which one 🙂
The conversation window is there at the bottom right but does not open when I click on it, probably because of a configuration not done on the hosting...
bosqweb Hi You can click on the Inbox button in toolbar and it will open the message box. the bottom right there is chatbar option that will display chat when you already have message from a member.
