Error intalling scripts

I did a fresh install of Centos 5.5 and a fresh install of Virtualmin. I restored some of my domains from backups.

I found a couple of issues and have worked on getting them fixed up. I was having trouble with Squirrelmail and phpMyAdmin. So I uninstalled them both from one of my domains and was going to reinstall them.

When I go to do that though, I get this error.

This script cannot be installed, as this virtual server does not meet its requirements : Could not work out exact PHP version

I installed the PHP 5, whatever version comes with CentOS. I have done all the updates, and there are not any for Virtualmin.

Any help would be greatly appreciated.

Thanks!
