Yes, but that’s not exactly a fix, but a workaround. The next time they change the code, you’ll have to update your site’s codes again, and you may never know when that will be. The best course of action is to contact them and let them know about the issue.
Apart from that, you’ll also have to add the !important bit for the footer, and any other elements the ratehub widget overrides. (And maybe add a title for your site – I don’t think it’s good for SEO if your front page site title is just ».)
