Problem:
In the Slovenian translation, when navigating to certain product categories, all product links and menu links lose the language name parameter (/?lang=sl). Deleting and recreating the translated product category did not resolve the issue.
Solution:
We recommend using WPML → Taxonomy Translation for translating taxonomies. If Yoast displays a warning about creating a redirect when editing a translated term, you can click “Undo” to remove the redirect. If a redirect has already been created, you can manually remove it from Yoast → Redirects.

Option 1: No changes to Yoast Premium (recommended)
Add the following snippet to your functions.php file:

add_filter( 'Yoast\\WP\\SEO\\term_redirect_slug_change', function( $create_redirect ) {
	// Only act in admin term edit contexts.
	if ( ! is_admin() ) {
		return $create_redirect;
	}

	$taxonomy = $_POST['taxonomy'] ?? '';

	if ( ! $taxonomy || ! taxonomy_exists( $taxonomy ) ) {
		return $create_redirect; // not editing a taxonomy term
	}

	if ( class_exists('Sitepress') ) { 
		$current_lang = apply_filters( 'wpml_current_language', null );  
		$default_lang = apply_filters( 'wpml_default_language', null ); 
		if ( $current_lang !== $default_lang ) {
			return true; // prevent Yoast redirect creation
		}
	}

	return $create_redirect;
}, 10 );

This prevents Yoast from automatically creating redirects for taxonomy terms in secondary languages.

Option 2: Modify Yoast Premium code
This involves editing core plugin files and is not recommended due to potential issues with future updates.

We plan to notify Yoast about this behavior. However, if this solution does not apply to your case or seems outdated, we highly recommend checking related known issues, verifying the version of the permanent fix, and confirming that you have installed the latest versions of themes and plugins. If the issue persists, please open a new support ticket.
