@AKAVAN I put the code below on every page that doesn't have an Ecwid store on it.
And the 2nd code below is put on every page with an Ecwid store on it.
I've done some CSS design changes you'll have to update or remove.
Code for pages without Ecwid Store
<div data-fixed-shape="RECT" data-layout="BIG_ICON_TITLE_SUBTOTAL" data-icon="cart" data-horizontal-indent="50px" data-responsive="FALSE" class='ec-cart-widget' style="color: #ffffff00;"></div>
<div>
<script data-cfasync="false" type="text/javascript"
src="https://app.ecwid.com/script.js?28194192&data_platform=code"
charset="utf-8"></script><script>Ecwid.init();</script></div>
