I update woocommerce today and have error 500. In logs I find this: include(WC_ABSPATHincludes/wc-conditional-functions.php)
Issue I found in files where used WC_ABSPATH like this:
include_once( WC_ABSPATH . ‘includes/legacy/abstract-wc-legacy-order.php’ );
But I dont find where WC_ABSPATH declarated. Also upper in code check other path:
if ( ! defined( ‘ABSPATH’ ) ) {
exit;
}
