I was working on development of www.ojaivalleycert.org, when after a couple hours it threw up a message saying that my version of PHP was incompatible with WordPress 3.2.1. I had php 4.x and it needed 5.x
After a quick search, I found I had to add this to my .htaccess file. Thanks 1and1.com!!
AddType x-mapp-php5 .php
