Overview of the issue

When WP Rocket is used on a site configured with WPML’s “Display as Translated” option, you will notice that when a post is translated the categories are not being copied, even though the option to “Copy taxonomies to translations” is enabled.


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

  • Add this code to your theme’s functions.php file:
    add_action('after_rocket_clean_post', function( $post ){
    		wp_cache_delete($post->ID, 'WPML_Cache_Terms_Per_Lang');
