Going to https took my live site down, running out of ideas

From everything I read, I'm looking to do a massive replace('http:','https:') So far I've changed all /public_html/wordpress/ files to https and the wordpress database(15,000 entries) replaced as well. Still running into issues on everything outside of my homepage. I think wordpress has some sort of redirect that is killing the css/javascript. https://efficiencyiseverything.com/wp-content/themes/ The moment anything goes deeper into content, pages stop loading. Thinking its a redirect loop hidden somewhere. Any ideas what to google? This is day 3...
