Thanks to Rob Branigin for spotting a problem in World Vital Records yesterday. I contacted the vendor and learned:
The reason you are unable to view the Newspaper Archives right now is because the site is under construction. They had a couple glitches happening and they are working on getting them fixed. The Newspaper Archives will be back up on the website, it is unfortunately an unknown date. But it is going to be sometime soon, from what I understand.
We’ll keep an eye out for the fix.
