404 error on article pages + footer issue

I’ve added the shortcode to the page to display the basic knowledgebase.

I then created two sample articles and two sample categories.

They are initially organized nicely but when you click on the example articles to drill down they load a broken 404 page.

Why isn’t it showing the article copy?

I’ve tried the permalink remedy that you mention in separate support topics but it didn’t fix the issue.

Second issue – when the shortcode is added to the page example noted in this topic you’ll see the footer get squished down horizontally. It’s supposed to be full width like on every other page.

The page I need help with: [log in to see the link]
