Wordpress issue when posting homepage link to Facebook

We have just launched a new WP website, www.yourtrainingsolutions.com.au. Everything is working fine, except when you post a link to this site (ie. [url removed, login to view]) to Facebook, the following appears as the title and description:

**WordPress ? Installation**

[url removed, login to view]

Welcome to the famous five minute WordPress installation process! You may want to browse the ReadMe documentation at your leisure. Otherwise, just fill in the information below and you'll be on your way to using the most extendable and powerful personal publishing platform in the world.

I don't know why this is happening! I have an SEO plugin installed and custom meta set for the homepage, which shows in code view when I check. This installation message does not show anywhere in the code :(

I need an experienced WP programmer who knows what this is caused by and can fix the site so that the meta that I have set for the homepage displays when I post the URL to Facebook (and also so that this is the meta that gets indexed by Google, not the installation message!).
