Remove the front of the variable number $fields in file woocommerce-checkout-manager.php:
if ( 1 == ($options[‘checkness’][‘wccs_opt_9’] ) ) {
unset($fields9[‘billing’][‘billing_state’]);
}
if ( 1 == ($options[‘checkness’][‘wccs_opt_10’] ) ) {
unset($fields10[‘billing’][‘billing_phone’]);
}
To:
if ( 1 == ($options[‘checkness’][‘wccs_opt_9’] ) ) {
unset($fields[‘billing’][‘billing_state’]);
}
if ( 1 == ($options[‘checkness’][‘wccs_opt_10’] ) ) {
unset($fields[‘billing’][‘billing_phone’]);
}
There are other variables incorrect, just have to remove the numbers also
