The values for the $WA_localRoot and $WA_remoteRoot variables are taken from your site settings.
The $WA_remoteRoot is taken from the HTTP Address you enter on the Local Info tab of youor site definition.
the $WA_localRoot is taken from the URL Prefix you set on the testing Server Tab.
For both of these variables, it takes any sub folders after the domain.
In your screen shots you have:
Local Info HTTP Address: LJackson
Testing Server - URL Prefix: ck4.org
Sothe variables would be written as:
$WA_localRoot = "/ck4k.org/";
$WA_remoteRoot = "/LJackson/";
Looking at your settings, the remote host is your testing server. for both the HTTP Address and the URL Prefix you should be entering "http://www.ck4k.org/"
Did you try entering either of the addresses:
into a web browser? I dont believe that either of them would have worked.
