Home page suddenly not full width

Hey there! This site was looking great until this morning. I was changing the social thumbnails in yoast, and when that was completed, the home page suddenly became slim. I’ve tried a ton of css and html edits, but I can’t make an impact no matter what I try.

Tried deactivating plugins, and everything is up to date. It’s probably an easy fix, but I’ve had my head in this site for too many hours. Would seriously appreciate even a pointer in the right direction. Thanks.
