I don't think v7.5 would support PHP 7.4 as it wouldn't have existed when v7.5 was developed and released - try dropping the PHP version down to PHP 7.2 or 7.3, or if you need to use PHP 7.4, then you might need to use v8 or later.

Would agree with @brian! , though looking at the error it seems the view cart template has PHP in it that is trying to access an object but that object has not been initialized .  Are you using a custom orderform?

have you made any changes to the templates ? specifically viewcart.tpl ??

if so, what happens when you use a clean (unaltered) version of Six and standard_cart ??

then you are using a custom theme and/or custom orderform template ?

the point is not so much whether you've made any changes to the template since updating, its whether those templates where updated before updating (e.g they're custom).

and if you wanted to templorarily view your cart using Six & SC, and didn't want to make changes to your WHMCS configuration, then you can pass the system template and orderform in the URL.
