String Translations Are Not Visible on the Site After a String Has Been Translated

Overview of the Issue

In some rare cases after updating from an older version, translations are not visible after you translate a string. This happens if the update and migration steps get stuck.

Workaround

Add the following code to your wp-config.php:

define( 'WPML_ST_SYNC_TRANSLATION_FILES', true );

Then back up your site and delete the stuck wpml_st_upgrade_in_progress transient with WP-CLI:

wp transient delete wpml_st_upgrade_in_progress
