Eoin,
Sorry for the delay. On your page, at the top, I'm seeing 2 MySQL errors. They are being placed before the opening html and head elements. I'd first try to determine the cause of that error or at lease disable Error Reporting on the front-end. Having text display outside the proper html locations can cause Javascript to go funky. The error is very generic though, so I can't tell what extension is throwing it.
Beyond that, there's a lot of JS errors on the page, all seeming to come from templates/corporate_response/js/s5_info_slide.js. I'm not sure what's causing those errors, but that script can't seem to find a lot of the elements it's looking for.
To disable JFBConnect or JLinked, I'd try disabling the system plugins for each of those. That will prevent the Javascript that we load from being inserted into the page and effectively disable them for your testing purposes. Obviously, check the output to make sure our JS is missing, but I think that will help eliminate (or narrow down) our extensions as the cause.
Let us know how it goes, and best of luck,
Alex
