Event Tickets Plus - Tickets do not appear on translated event pages

Overview of the issue

When you are using the Event Tickets Plus plugin to create a new event and add tickets to it, the tickets section does not appear on the translated event page.

Workaround

Please, before proceeding, make a full backup of your site:

1. Add the following snippet to WPML → Settings → Custom XML Configuration:

    <wpml-config>
       <custom-fields>
           <custom-field action="copy">_ticket_end_date</custom-field>
           <custom-field action="copy">_ticket_start_date</custom-field>
           <custom-field action="copy">_tribe_ticket_capacity</custom-field>
           <custom-field action="copy">_tribe_ticket_show_description</custom-field>
           <custom-field action="copy">_tribe_ticket_version</custom-field>
           <custom-field action="copy">_tribe_tickets_ar_iac</custom-field>
           <custom-field action="copy">_tribe_tickets_meta</custom-field>
           <custom-field action="copy-once">_tribe_wooticket_for_event</custom-field>
       </custom-fields>
   </wpml-config>

2. Add the following code to the functions.php file:

    
   //WPML Workaround
   add_action( 'save_post', 'wpmldp_update_tribe_wooticket_for_event_meta', 999,3 );
    
   function wpmldp_update_tribe_wooticket_for_event_meta( $post_id, $post, $update ) {
   	// Only set for post_type = product
   	if ( 'product' !== $post->post_type ) {
   		return;
   	}
   	//Check if WPML and THe Events Calendar are enabled
   	if (class_exists('SitePress')) {			
   
   		//Get the current ID on "_tribe_wooticket_for_event" meta
   		$current_wooticket_id = get_post_meta($post_id, '_tribe_wooticket_for_event');
   
   		if ( $current_wooticket_id ) {
   			//Get Post Language
   			$wpml_post_language_details = apply_filters( 'wpml_post_language_details', NULL, $post_id ) ;
   			$wpml_current_language = $wpml_post_language_details['language_code'];
   
   			//Check if there is a translation for the $current_wooticket_id. If not, returns the original ID
   			$translated_wooticket_id = apply_filters( 'wpml_object_id', $current_wooticket_id[0], 'tribe_events', FALSE, $wpml_current_language);
   
   			//Update post meta with the translated ID
   			if ($translated_wooticket_id) {
   				update_post_meta( $post_id, '_tribe_wooticket_for_event', $translated_wooticket_id );
   			}			
   		}		
   
   	}
   	return;
   }
   

3. Create the event, and add tickets to it.
4. Translate the event.
5. Go to Products → All Products and edit the ticket.
6. Do a small modification on the ticket and save.
7. Translate the ticket. Keep in mind that if the event already exists, you just need to translate it before translating the ticket. If both are already translated, do a small modification on the original ticket, then update the translation.

If you are using The Events Calendar plugin, you will need to change this line:

 $translated_wooticket_id = apply_filters( 'wpml_object_id', $current_wooticket_id[0], 'page', FALSE, $wpml_current_language); 

To:

 $translated_wooticket_id = apply_filters( 'wpml_object_id', $current_wooticket_id[0], 'tribe_events', FALSE, $wpml_current_language);
