If you can't see the dashboard on the Joomla admin area maybe you have a conflict with another extension.
We found that when you have installed the sobipro this can cause the problem.
The solution is uninstall the SobiPro and install the LiveHelp Server and setup, without SobiPro the dashboard should be work fine.
Install the LiveHelp Server in a sub-domain or sub folder with a basic joomla installation and from there manage your sites, this is a very common way that many users use. example : livehelp.mysite.com
