I have attempted doing the SSL through the admin site, but it doesn't actually force all users to HTTPS, they still have the option to use HTTP. It does change all of the links to HTTPS so if a user clicks anywhere on the site it will use HTTPS. If anything I will have to settle with this.
Abantecart version is 1.2.10.
Only English installed.
Not sure what is causing the issues, maybe it's unique to my situation.
