I have a site for a client that is behaving very strangely. You can view the site here http://cruisephotofactory.com
When you click the like button in the sidebar instead of using the open graph values the site gives, FB posts the text from the WordPress install screen. This text is 100% not on the site anywhere and anyway the only time it appears is during install, when obviously the FB button was not yet installed or active.
I have the same site, same code, same theme, same everything installed on a second domain http://cruisephotofactory.it and here I would expect the same thing to happen, only it doesn't. instead it seems to post the wp object on the FB wall.
If I clone the site to a different domain on a different server, everything works fine the problem only seems to be happening on these 2 domains.
I am sure it has to be something blindingly obvious I am missing and I am going to feel really stupid when its pointed out, but blasted if I can figure out how 2 different, repeatable outcomes are happening with the same code and how its getting the install text in the first place!
