Are you still having issues? When I hit the page earlier (in Chrome I think), I never saw the error. If you're saying it was breaking your site -always-, I wasn't able to see that.
Right now, it's loading for me just fine, and I even tried to register this time without issue. Let us know if you're still running into issues, and if so, how to recreate them, cause now I'm a little confused
P.S. I like the modal pop-up for system messages.. looks really nice.
