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.
Workaround
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'); });
