HUSKY - Products Filter Professional for WooCommerce - Product Category Links Not Correctly Translated

Overview of the issue

When using HUSKY – Products Filter Professional for WooCommerce with WPML, there is a known issue where product category links like the following are not correctly translated.

For example, translating http://www.domain.com/product-category/slug1/slug2/slug3, results into http://www.domain.com/?product_cat=slug3, instead of having: http://www.domain.com/en/product-category/slug1/slug2/slug3.
This issue results in URLs that do not resolve correctly in secondary languages, leading to 404 errors.

Workaround

Please, make sure of having a full site backup of your site before proceeding.

• Add the following code to the theme's functions.php file:

  // WPML Workaround for compsupp-7532
  function wpml_compsupp7532_add_custom_blacklist_requests( $blacklist, $sitepress ) {    
  	// Add your custom request to the blacklist array
  
    // We can hardcode URL's, like:
    // Add here your problematic URL's
    $blacklist[] = "category-product/slug1/slug2/slug3";
      
    return $blacklist;
  }
  
  add_filter( 'wpml_sl_blacklist_requests', 'wpml_compsupp7532_add_custom_blacklist_requests', 10, 2 );
  

• Add a small modification to the block content.
• You may need to re-translate the links.
