Problem: The client was experiencing an issue where after switching languages using the header language switcher and selecting a child category from the sidebar menu, all other child category menus displayed incorrect product_cat slugs in their links. The problem seemed to be related to the WordPress 6.5 localization changes but was resolved after updating WPML Multilingual CMS from 4.6.9 to 4.6.10.
Solution: We recommended the following steps: 1. Check for any code-based rules applied to the categories and remove them if possible. 2. Remove any untranslated elements added in the code for the Archive page and revert any custom changes to display WooCommerce's default Category archive. 3. Add the default Product Category widget in the sidebar and re-evaluate the situation. 4. If using the
get_queried_object_id()
function to display terms, use the wpml_object_id hook to ensure the correct taxonomy ID is retrieved in each language.
We also noted that support for issues arising from custom themes or code modifications is beyond our scope, and suggested consulting with the theme developer or hiring a WPML-experienced developer from our contractors.
