WooCommerce Translation Not Working After .po/.mo Upload

Hello, Jae,

Thank you for disabling caching as requested.

We would like to inform you about an issue related to translation file loading. The Loco Translate plugin is currently attempting to load translation files from the root directories of themes and plugins, even though the translation directory is set to “System” in its settings. As a result, all translation changes are being saved in the system directory, but not being properly applied.

This leads to a conflict where, for example, you configure a translation in the file:

wp-content/languages/themes/xstore-zh_TW.po

However, the system is actually loading the file:

wp-content/themes/xstore/languages/ch_TW.mo

The same issue applies to plugin translations as well.

To address this, we have temporarily added the following code to the functions.php file of your child theme to ensure the correct translation files are loaded for our theme and WooCommerce:

add_action( 'after_setup_theme', function() {

    if ( get_locale() !== 'ch_TW' ) return;

    unload_textdomain( 'xstore' ); 
    load_textdomain( 'xstore', WP_LANG_DIR . '/themes/xstore-zh_TW.po' );

    unload_textdomain( 'xstore-child' ); 
    load_textdomain( 'xstore-child', WP_LANG_DIR . '/themes/xstore-child-zh_TW.po' );

    unload_textdomain( 'xstore-core' );
    load_textdomain( 'xstore-core', WP_LANG_DIR . '/plugins/xstore-core-zh_TW.po' );

    unload_textdomain( 'woocommerce' );
    load_textdomain( 'woocommerce', WP_LANG_DIR . '/plugins/woocommerce-zh_TW.po' );
});

Please note that this solution only partially resolves the issue, as there are other plugins installed on your site whose translations are still not functioning correctly.

We recommend reaching out to the developers of the Loco Translate and Polylang Pro plugins to report this issue and seek further assistance.

Additionally, we have included the following (currently commented out) code in your child theme’s functions.php file. This code can help track which translation files are being loaded. You can monitor this information in your site’s error_log file, as well as in the private content section of this message:

add_filter( 'load_textdomain_mofile', function( $mofile, $domain ) {
    error_log( "Loading MO file: $mofile for textdomain: $domain" );
    return $mofile;
}, 10, 2 );

Should you have any further questions or require additional assistance, please do not hesitate to contact us.

Best regards,

Hello, Jae,

1) You can find this information in the debug_log file.

2) The specified code has already been added. As you can see on the single product page, the data related to our topic or Elementor has been translated. However, the strings related to other plugins remain untranslated:
