You are right. You have the SSL which expires in October – https://snipboard.io/n7esNt.jpg
So it should not show http error. The reason it is showing errors is because you are having mixed content. Some of the asset (images, css, js) files are being called with http and some are with https hence the browser shows http error.
To resolve this you will need to search-replace http URLs with https. You can do it in two ways:
1) Using a search replace plugin like this – https://ww.wp.xz.cn/plugins/better-search-replace/ In the search for field you need to input http://childorthocare.com/ and in the replace with field you need to input https://childorthocare.com/
2) Using a WP-CLI command like below:
wp search-replace "http://childorthocare.com/" "https://childorthocare.com/"
Please ensure you take the website backup before you do this. Hope this helps.
