Perch Shop Checkout Localhost vs. Hosting

I'd have to ask my hosts. Is there some info that I can provide them which might help diagnose the problem. i.e. how is the user logged in, is it php sessions? Obviously they will be unfamiliar with Perch therefore it would be helpful to explain in the most basic terms what I am trying to achieve and how it might be supported on their server

Yes compatibility test passed on this sever, so maybe not to do with sessions?

I would assume so but I can contact support to make sure. I'm developing locally on MAMP and the host is basic shared hosting with www.lcn.com.

I contacted them yesterday and they confirmed that sessions are enabled by default and since then when I checkout a Customer is created but the Order is not created?

Can test by checking out from here (after adding a Fabric swatch to basket): https://test-chase-erwin-com.php5.hostingweb.co.uk/basket

My shop-checkout.php page is this:

<?php
    if (perch_member_logged_in()) {
        // your 'success' return URL
        $return_url = '/order-complete';
        $cancel_url = '/basket';

        perch_shop_checkout('manual', [
            'return_url' => $return_url,
            'cancel_url' => $cancel_url,
        ]);
        echo '<h1>Logged in</h1>';
    } else {
        echo '<h1>Not logged in</h1>';
    }
?>

But for some reason perch_shop_checkout() is not being called? This still works as it should when testing locally, but not on the hosted server.

perch_member_logged_in() is now working and the Customer is created, but no Order is created so it appears perch_shop_checkout() is failing on this server.

After adding debug to the checkout page I can see there is an error with the Address and Shipping missing? Since I am using customer_create_passwordless.html to create the Customer and then initiate the Checkout by using next="/shop-checkout" on that create customer form, is there something I need to do to associate the address added to that form, with the Order address? Again, this all works locally, but is maybe causing the issue on the server?

How do you mean new setups? As in new installs going forward, or I can update and it may fix?

Ok thanks Drew. So I hold fire on updating?

This is the last remaining item before go-live, do you have any indication of how long it might take so I can manage my clients expectations?
