 * Hi,
 * I’ve noticed there’s a plugin conflict with Checkout Field Editor for WooCommerce
   plugin ([https://en-gb.wordpress.org/plugins/woo-checkout-field-editor-pro/](https://en-gb.wordpress.org/plugins/woo-checkout-field-editor-pro/))
 * When both plugins are active no new order or processing order emails are being
   send. The following fatal error occurs.
 * [Wed May 24 09:36:01.612045 2023] [proxy_fcgi:error] [pid 18848:tid 140694832031488][

 * When I disable Order Weight for WooCommerce emails are being sent. When I disable
   Checkout Field Editor for WooCommerce plugin and Order Weight for WooCommerce
   is enabled emails are also being sent.
 * I will also report it in Checkout Field Editor for WooCommerce plugin forum.
 * Please assist.
 * Cheers,

 * Hi Jaap,
   Thanks for letting me know – I will investigate this further.I can see
   in the [other thread](https://wordpress.org/support/topic/plugin-conflict-392/)
   that you got help from their support and that you managed to solve it, care to
   share the solution?

 * Hi [@andreaskarman](https://wordpress.org/support/users/andreaskarman/), ThemeHigh
   sent me some replacement files for their plugin and a snippet:
 * add_filter(‘thwcfd_email_order_meta_fields_priority’, ‘th_change_email_order_meta_priority’);
   
   function th_change_email_order_meta_priority(){return 9;}
 * It did happen in the past too and they also solve it back then.
 * Cheers,
 * Jaap
