There is a conflict. If you open the HTML on that page and search for 'all.js', you'll see it multiple times. That's Facebooks Javascript API and should only be loaded once. It looks to be associated with the Like button your using on that page.
If you can remove the extra calls to the all.js script, that should solve your problem. If not, definitely let us know!
As for the Like button placement, if necessary, you can modify their template (or wherever they're adding the Like button), and replace their code to insert the Like button with {JFBCLike}. Of course, if you're there already, hopefully, you can just remove the all.js inclusion and that will be it.
Thanks,
Alex
