Inconsistent Theme & Menus

Hi there,

Hoping you can help.

I have been trying to clean up the website, and pick 1 theme to use (Nature?), but it seems to have remnants of the IIdly theme.

At this point, either theme will work ok.

But we need all the pages to look like the HOME page. Instead they all show a Pageside bar. I cannot get rid of the page sidebar no matter which theme I pick. I also tried elementor too but I can uninstall that.

Can you help me clean this up, and just have one theme working ok and not have pages with side bars?

Thanks so much!
