This commerceOrder has been previously paid (php Error)

Hi Pascual,
Please make sure the billing and shipping country field is not removed from Checkout.

Thanks for the reply. I tried that but am now getting another similar error. My checkout setup is basically the following: It is a gift shop so we have the billing section only be first and last name, telephone and email. And the shipping section includes all the details of the person receiving the gift – first and last name, telephone and address fields. It seems like no fields can be hidden for the plugin to work? Would appreciate any help on this. Thanks again, condless.

I have the following fields unset in my theme functions.php file because we don’t use them.

    unset($fields['billing_address_1']);
    unset($fields['billing_address_2']);
    unset($fields['billing_state']);
    unset($fields['billing_city']);
    unset($fields['billing_postcode']);
    unset($fields['shipping_postcode']);

Here is the new error I am getting:

Hi,
Please try to make the following modifications in the plugin’s main file:

Replace this:

if ( in_array( $data['billing_country'], get_option( 'wc_csz_countries_codes' ) ) ) {

with this:

if ( isset( $data['billing_country'], $data['billing_state'] ) && in_array( $data['billing_country'], get_option( 'wc_csz_countries_codes' ) ) ) {

and replace this:

if ( in_array( $data['shipping_country'], get_option( 'wc_csz_countries_codes' ) ) ) {

with this:

if ( isset( $data['shipping_country'], $data['shipping_state'] ) && in_array( $data['shipping_country'], get_option( 'wc_csz_countries_codes' ) ) ) {
