 * Hi,
 * We have PHP errors in our debug.log file – one of the returning errors seems 
   to be related to the WooCommerce Gateway Stripe plugin:
 * `billing_first_name was called incorrectly. Order properties should not be accessed
   directly.`
 * The backtrace shows:
 *     ```
       Backtrace: 
       require('wp-blog-header.php'), 
       wp, 
       WP->main, 
       WP->parse_request, 
       do_action_ref_array('parse_request'), 
       WP_Hook->do_action, 
       WP_Hook->apply_filters, 
       call_user_func_array, 
       WC_API->handle_api_requests, 
       do_action('woocommerce_api_wc_stripe_subs_compat'), 
       WP_Hook->do_action, 
       WP_Hook->apply_filters, 
       call_user_func_array, 
       WC_Stripe_Subs_Compat->stripe_checkout_return_handler, 
       WC_Gateway_Stripe->stripe_checkout_return_handler, 
       WC_Stripe_Subs_Compat->process_payment, 
       WC_Gateway_Stripe->process_payment, 
       WC_Stripe_Payment_Gateway->process_response, 
       WC_Order->payment_complete, 
       WC_Order->save, 
       WC_Order->status_transition, 
       do_action('woocommerce_order_status_pending_to_processing'), 
       WP_Hook->do_action, 
       WP_Hook->apply_filters, 
       call_user_func_array, 
       WC_Emails::send_transactional_email, 
       do_action_ref_array('woocommerce_order_status_pending_to_processing_notification'), 
       WP_Hook->do_action, 
       WP_Hook->apply_filte in /nas/content/live/[...]/wp-includes/functions.php on line 4667
       ```
   
 * Could you please investigate this further?
 * Thanks,

 * Hi,
 * Are you seeing any errors on the front end and is this effecting the operation
   of your website in any way. Are you just seeing this message in the logs?
 * Many times when we have seen this in the logs, it’s due to either a conflicting
   plugin or a template file that is out of date.
 * Are all your template files up to date?
 * Thanks!

 * Hi Shane,
 * Thanks for your quick response – it took some time to review the whole plugin
   infrastructure, and now we see that there are indeed some plugins incompatible/
   not tested with the recent WooCommerce version, and we also have some outdated
   custom templates.
 * So – I’m closing this ticket now. If after fixing everything we still see the
   error in the debug.log file, I’ll open a new one – but I agree, most probably
   the fixes will make the error go away.
 * Thanks again,
    Lunule
