Pierre,
Not sure what happened. The other pages are loading now, except the main "Sea Foam" one. Internet burp.
On the Sea Foam one, I Liked it and it worked fine.
Unliked though, I basically see a dot in the top left corner and a blank white page. The really strange thing (see attached picture) is that content from your site
-is- loading. However, the only content that's coming through is the dot (see the inset image at the top in the HTML) and then there's a RokBox in the main content area which has no content excluding a "Close [x]" button:
Not sure what the RokBox is doing. It's possible that's just a gate on your site that's covering other content from showing.. or not. Hopefully, it helps somehow though. Unfortunately, Facebook doesn't show us the URL it 'thinks' it's pulling from, or that would obviously help. Maybe this will help you understand things though.
As for suggestions:
* Try a different template (to see what happens)
* Disable the RokBox and see what happens
Not sure what else to say, since content is being loaded...
