Overview of the issue

You may experience an ERR_TOO_MANY_REDIRECTS error when using WPML Multilingual & Multicurrency for WooCommerce while setting product permalinks to Shop base with category.

This issue occurs when products are set to Translatable – use translation if available or fallback to default language, and product categories are also translatable. When switching to a secondary language, the translated product URL fails to resolve correctly, causing an infinite redirect loop.

Workaround

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

• Open your theme’s function.php file.


• Add the following code:

  add_filter( 'wc_product_post_type_link_product_cat', 'custom_modify_product_cat', 10, 3 );
  
  function custom_modify_product_cat( $primary_term, $terms, $post ) {
  	// Example: Replace the primary term if the product has a specific category
  	if ( $post->post_type === 'product' ) {
  		foreach ( $terms as $term ) {
  			$termid = apply_filters( 'wpml_object_id', $term->term_id, $term->taxonomy, TRUE  );
  			$term = get_term( $termid, $term->taxonomy );
  			return $term;
  		}
  	}
  	return $primary_term;
  }
