Go to System → Settings → Store Details
Include the full secure URL to your store. Make sure to add '/' at the end. Example: https://www.yourdomain.com/path/ or https://www.yourdomain.com/
Insecure URL starting from HTTP is for testing only. HTTPS provides a secure browsing experience by encrypting data and cookie-sending behavior.
Store Url created automatically after AbanteCart installation, modify it only if you move your store to another folder or change domain name.
Secure Store URL
This will be the URL used during the viewing of secure store pages (login, my account, checkout, etc) via HTTPS protocol. Include the full SSL URL(HTTPS) in your store. Make sure to add '/' at the end. Example: https://www.yourdomain.com/path/
You can set a separate domain for secure connections (shared SSL domain). To use SSL check with your host if an SSL certificate is installed.
