Installing and upgrading help

I am having the dreaded blank page problem with my moodle installation on my Jumpline VDS host. I have been through the httpd.conf, php.ini and config.php files and read the FAQ about blank pages.

http://xx.xx.xx.xx/moodle/admin/    > blank page
http://xx.xx.xx.xx/phpinfo.php        > php 4.2.3 info page OK looks like mysql and apache                                                             1.3.x support is there

I am using just an IP address as the site address, not a domain name until I know I can get this set up. If anyone else has had experience with this hosting plan, I'd be grateful for tips.
