How to remake cart in OpenCart?

Question

Apache HTTP Server

I welcome everyone! I have a small site on Opencart and there is a small problem with its basket.
I'm telling! I redid the shopping cart. Those. removed unnecessary steps and reduced them to two. BUT! when a person makes a purchase and goes directly to the shopping cart page, he stumbles upon an accordion. The first of the two remaining steps should be visible by default, meaning the accardion should be open. The person entered his data, pressed the button and the second step opens, the first one closes ...
But my first step is closed. You have to click on it yourself, which is not entirely true.

Answer 1

Is this port even being listened on by the http server? What http server is being used? Is there a certificate for encrypting traffic on port 443?

Answer 2

accordion-toggle - aria-expanded="true"
