Problem:
The client was experiencing 404 errors on product category pages in languages other than Dutch. The issue was due to incorrect URLs being generated for these categories, which also affected the menu links in these languages.
Solution:
We resolved the issue by adjusting the base slugs for each language. Here's how we did it:
1. We identified that the Dutch base slug was 'product-categorie' and the German one was 'produkt-kategorie'. For English, since the same slug as Dutch was initially used, we changed it to 'product-category' to avoid duplication.
2. We translated the category base slugs in WPML -> Taxonomy Translation and the default store URLs in WooCommerce -> WCML -> Store URLs.
3. We also addressed a problem with writing to the .htaccess file by creating a default .htaccess file using FTP.
After these adjustments, the URLs for the product categories were corrected across all languages, and the menu now reflects the correct URLs.
