After upgrading from Newspaper 7.x to Newspaper 12.x, main page not displaying c

After upgrading from Newspaper 7.x to Newspaper 12.x, main page is not displaying correctly, showing shortcode instead of main blog. What did I do wrong? How can I fix? Site is at tigardlife.com. Our other site is at tualatinlife.com and is rendering correctly after upgrade.

Background: Tualatin Life was upgraded from version 11.x to 12.x (not from 7.x) without problems. Additionally, we upgraded WordPress to latest version, upgraded php to version 8.0. Version 7.x broke the site after making updates, we could not login to wp-admin, so we upgraded both WordPress and theme via FTP, thinking that would fix the problem. That did allow the site to come up, but now we are having the rendering problems.

Thank you! That did the trick! 🙂 I’m having one more small problem I’ll ask in a separate post.
