correction to last reply
sorry, the values specified as above are just some of all the options I have tried, and have been changed since last updated to the server. The values corresponding to the image path specified as above are:
$WAGLOBAL_Root_URL = "http://studio-n.se/" ;
$WAGLOBAL_localRoot = "/CMS100/";
$WAGLOBAL_remoteRoot = "/CMS100/";
$WAGLOBAL_Images_Folder = "../images/";
As far as I can see, no additional folders have been created.
