Every PinnacleCart has its own unique login page. The address to your carts admin login page will depend on the domain you have on your account and whether or not the DNS for that domain is pointing to us.
https://example-xxx.mypinnaclecart.com/login.php (replace "example" with your actual domain and "xxx" with your domain's actual TLD extension such as .com, .net, etc)
If you have purchased a dedicated SSL Certificate for your domain, your carts admin login page will be:
https://www.example.com/login.php replace "example.com" with your actual domain)
