If you install and configure your LiveHelp Server and you can't start the comunication between the Support Panel windows console an the LiveHelp Server.
If when you try to start the Support Panel windows console this generate the follow error message : "The Support Panel cannot communicate with the server application: HTTP/1.1 406 Not Acceptable" this happens because the firewall in your server block the incoming comunnications with your server.
it’s most likely the result of something triggering a rule in the server's "mod_security" rules. AWH uses mod_security to block hijack attempts and known attacks against the server, but sometimes it gets triggered by mistake. This can happen if something on your site (like a URL) matches a string we filter on. A quick way to resolve this is to put the following in a .htaccess file in your web site's /home/username/public_html directory: SecFilterEngine Off
This will disable mod_security for your domain.
If you can fix this issue, you need to contac your server administrator and request include some permissions in the mod_security.
