I carried out the install, got everything setup OK using install.php then bombed out uploading the country.sql file so I started again and uploaded the data for the country-ip sql bit by bit using PHPMyAdmin and then tried the index.php, all I get is a blank page. I tried the radmin/index.php and again got a blank page.
Here is my paths from config.php
$CONFIG->wwwroot = "/home/webmon/public_html/randomizer";
//Site URL -please use the "http://www.mysite.com" format.
$CONFIG->siteurl = "http://www.webmoneyspinner.com/randomizer";
//Edit below ONLY if you changed the current site structure
$CONFIG->templatedir = "$CONFIG->wwwroot/templates";
$CONFIG->libdir = "$CONFIG->wwwroot/lib";
$CONFIG->imagedir = "$CONFIG->wwwroot/rimages";
