[Resolved] .mo Polish translation file for WooCommerce isn't working.

Problem:
The client was trying to enable the Polish translation for WooCommerce by following a guide and uploading the .mo file to the

/languages/woocommerce

directory, but the strings remained in English.
Solution:
We found that the translation should load automatically from WooCommerce. However, there is a known issue where translations do not load when using the block cart and block checkout if

WP_PLUGIN_DIR

and

WP_PLUGIN_URL

are defined in

wp-config.php

. To work around this problem, we recommend:
1. Using the

[woocommerce_cart]

shortcode on the cart page instead of blocks.
2. Removing the

WP_PLUGIN_DIR

and

WP_PLUGIN_URL

definitions from

wp-config.php

and using the standard plugins folder.

Please note that this solution might be outdated or not applicable to your case. If the issue persists, we highly recommend checking the related known issues, verifying the version of the permanent fix, and confirming that you have installed the latest versions of themes and plugins. If you still need assistance, please open a new support ticket.
