E_Error whenever WC()->cart->get_cart() is called

(@danielmoorehbd)

Hi,

Every day, the website will email me this once, the code works and I can’t figure out what the “trigger” is, the line it complains about looks fine to me, I can’t understand what it’s trying to say!

Any help would be appreciated:

Maybe it is similar to this: https://wordpress.org/support/topic/php-warning-implode-invalid-arguments-passed/

I think there should be a check if “something” is empty first.

Everywhere where “WC()->cart->…” is called, there has to be a check if the cart is empty/null. For example:
```
if(!is_null(WC()->cart)) {
    echo WC()->cart->get_cart_total();
    echo WC()->cart->get_cart_contents_count();
} else {
    echo ‘0’;
}
```
