Problem:
You are trying to make products visible on the frontsite after selecting a language using WPML. Products are visible in the original language but only on the backsite, not on the frontsite, after WPML language selection.
Solution:
We recommend checking the translation of the product category base. The issue might be due to the original product URL containing '/product-category/', while the translated versions use '/product-categorie/', which could be incorrect or inconsistent. Please go to WPML → String Translation and consider deleting the translation for 'product-category'. Ensure you back up your database before making any changes.

If this solution does not resolve your issue or seems irrelevant due to being outdated or not applicable to your case, we highly recommend checking related known issues at https://wpml.org/known-issues/, verifying the version of the permanent fix, and confirming that you have installed the latest versions of themes and plugins. If the problem persists, please open a new support ticket at WPML support forum for further assistance.
