Security certificate out of date?

I’m trying to access the IPUMS-I online analysis. However, I can’t seem to do so. Whenever I click on any of the country census options, I cannot proceed, and my browser says that the page’s security certificate is out of date. I’ve tried this on Chrome, Firefox, and IE, and they all give the same error. I do not have this error on any other website or for downloading microdata, but it makes initial data exploration a lot harder. Am I doing something wrong?

Thanks for alerting us to the issue. The certificates have been updated and you should be able to access the online tabulator again.
