On the left I use tabs (using the code for Tabber tabs, but not the plugin. Here’s the CSS for the tabbertabs (the code for the pages can be seen in view source): https://www.jrothraministries.com/blog/wp-content/themes/ministry-theme-by-John/ministry-theme/tabs.css

I’ve physically checked all the divs on that post (printed out the entire source code and manually marked them off) and found none left open. I have NO idea what would cause this problem except maybe it’s on the tab’s javascript (not familiar with that, but it’s here): https://www.jrothraministries.com/blog/wp-content/themes/ministry-theme-by-John/ministry-theme/javascript/tabber.js
