Hi, have just set up zen cart but on attempting to access admin via

https://localhost:8888/zen-cart/admin/login.php

I get

Safari can’t open the page.
Safari can’t open the page “https://localhost:8888/zen-cart/admin/login.php” because it couldn’t establish a secure connection to the server “localhost”.

on
http://localhost:8888/zen-cart/admin/login.php

it goes to login/ password page

please help!
