R – sIFR: visible on local, not remote

localsifrview

When working on a static mirror of the site, the sIFR is rendered correctly using Dreamweaver's live view. When viewing site locally in a browser, the regular text is printed, as expected. However, when uploaded and viewed from a remote web server, neither is visible.

I am using version 3 of sIFR, and the site can be viewed here, with an example page employing siFR implementation:
http://www.thevulgarbulgar.com/TEMP/rush/vacancies.html

Whereas it should look like so:

rush.co.uk/vacancies

Thanks for looking.
