template error on index page

Major problem began occuring last night and I can’t figure it out. No matter what I post, my blog’s main page loses its navigational/sidebar content.

example: https://everythingbetweeen.com

on single post pages it turns out ok: https://www.everythingbetween.com/index.php/2006/01/17/wiretapping-lawsuits-filed-dr-king-rolls-over/

Has anyone else encountered this and what’s my remedy?

thanks.
