Hi there,

Love this plugin – thank you 🙂

I am having trouble with the Webhooks however on one particular website, they’re all failing with a server 500 error.

These are the logs:

2021-11-29T00:00:06+00:00 CRITICAL Uncaught Error: Call to a member function get_cart_contents_count() on null in /home/******/******/***.***.co.uk/www/wp-content/themes/***/***/woocommerce-cart-custom-data.php:153

#7 {main}
  t in /home/******/******/***.***.co.uk/www/wp-content/themes/***/***/woocommerce-cart-custom-data.php on line 153

This isn’t a theme that I developed, but the part of the file it’s referring to is:

add_filter('wp_loaded', function () {
    if (!is_admin()) {
***     if (WC()->cart->get_cart_contents_count() == 0) {
            WC()->session->__unset('cart_created_time');
        } else {

            // items in cart.
            $cartCreatedTime = WC()->session->get('cart_created_time');

            if (!$cartCreatedTime) {
                WC()->session->set('cart_created_time', time());
            }
        }

        check_session();
    }
});

I highlighted line 153 with ***.

Is this something you could help me with please?

Thanks so much.

Hi @andreajbradley,

The error, as you have pointed out, is being caused by your theme, not the Stripe plugin.

The reason this error is being encountered is your theme is calling WC()->cart which is only instantiated for frontend requests, not REST requests.

Your theme should have an additional check to make sure either the cart exists or this isn’t a REST request.

Something like this:
```
if(!is_admin() && WC()->cart){

}
```
Kind Regards,

Different topic – and not sure if the theme is to blame again – but the refund button on the order page prints the buttons text with <span class=”currency”>£</span>.

It’s not causing any issues but just an FYI

Thanks again for your help today.

Hi @andreajbradley,

The Stripe plugin does not render the refund button so it would be some other functionality that’s causing the html to be rendered as text.

I thought that might be the case, thank you for coming back to me 🙂
