[Resolved] 404 error on Spanish product category pages.

Problem:
The client was experiencing 404 errors on Spanish product category pages on a multilingual site using WPML, despite the products being visible and unique slugs for categories being set. The default language was Dutch, and the issue persisted even after re-saving permalinks and disabling caching/SEO plugins.
Solution:
We identified that the issue was due to the client setting a custom base but using a different shop slug. We recommended using the original shop page slug 'winkel' and the regular WooCommerce permalink setting 'Shop base with category'. We adjusted the permalink settings from Settings > Permalinks to resolve the issue. After making these changes, the Spanish product pages began to display correctly.
