Known issue

Problem:
The client is experiencing an issue where email notifications sent from their multilingual e-commerce sites viviscal.bg and viviscal-store.com are displaying in multiple languages instead of just the language in which the order was made. This problem is linked to the YAY Mail plugin's handling of languages.
Solution:
We recommend updating the YAY Mail plugin's code to ensure that emails are sent in the correct language. Specifically, modify the

get_site_language

function in the WPMLIntegration.php file. Here's the step-by-step guide:

1. Backup the original WPMLIntegration.php file located in /wp-content/plugins/yaymail-pro/includes/Integrations/Translations/.
2. Replace the existing

   get_site_language

   function with the following code:

   public static function get_site_language( $order ) {
           global $sitepress;
           $language = \defined( 'ICL_LANGUAGE_CODE' ) ? ICL_LANGUAGE_CODE : 'en';
           if ( null !== $order || isset( $GLOBALS['yaymail_set_order'] ) ) {
               $order_data = ( null !== $order ) ? $order : $GLOBALS['yaymail_set_order'];
               // $order_language = $order_data->get_meta( 'wpml_language' );
               $post_language_details = apply_filters( 'wpml_post_language_details', null, $order_data->get_id() );
               $order_language        = isset( $post_language_details['language_code'] ) ? $post_language_details['language_code'] : '';
               if ( ! empty( $order_language ) ) {
                   $language = $order_language;
               }
           }
           $sitepress->switch_lang( $language );
           return $language;
       }

   with

   public static function get_site_language( $order ) {
       global $sitepress;
    
       // Use default language as safe fallback
       $language = apply_filters( 'wpml_default_language', null );
    
       if ( null !== $order || isset( $GLOBALS['yaymail_set_order'] ) ) {
           $order_data = ( null !== $order ) ? $order : $GLOBALS['yaymail_set_order'];
    
           $order_language = $order_data->get_meta( 'wpml_language', true );
    
           if ( ! empty( $order_language ) ) {
               $language = $order_language;
           }
       }
    
       do_action( 'wpml_switch_language', $language );
       return $language;
   }

3. After updating the code, test the email notifications to ensure they are now sent in the correct language.
