Loading mixed content while using HTTPS

Hello, I have done a lot of google searches and forum searches to try and fix an issue I am having with my website. I am trying to set up https: and I do have an SSL certificate installed, but it seems to not be encrypting some images. There also seems to be an issue loading some java scripts.
When I inspect the element on the webpage I see a lot of things not loading because its trying to load content over http while the site is loading in https, so that content wont be displayed.

Mixed Content: The page at ‘https://www.hillarylouise.com/’ was loaded over HTTPS, but requested an insecure script ‘http://www.hillarylouise.com/wp-includes/js/wp-emoji-release.min.js?ver=4.3.1’. This request has been blocked; the content must be served over HTTPS.

There are several other scripts being blocked but they all say the same thing. There is also a lot of images being blocked and they are doing the same thing the scripts seem to be doing – trying to use http instead of https.

I logged into the cPanel and searched through several .php files and made manual changes of removing the “http://hillarylouise.com section so it will look like <img src=/wp-content/blah blah

However, even though I found and edited probably 100 things, I can not seem to fix these errors.
I’m not sure what else to do! Any help would be appreciated.

Thanks!
