[Redis Object Cache] – Theme & Plugin Localization Scan Only Localizes New Strings After Clearing Object Cache

Overview of the Issue

If you are using WPML with Redis Object Cache plugin, you might encounter a problem where the Theme & Plugin Localization scan only localizes new strings after clearing the object cache manually. Specifically, when you delete a string from WPML → String Translation page, and scan the theme again, the deleted string doesn’t get re-added to String Translation unless you clear the Redis Object Cache first.

Workaround

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

• Open your theme’s functions.php file.
• Add the following line:

  //workaround compsupp-7057
  add_action( 'wpml_st_before_remove_strings', 'wp_cache_flush' );
