Problem:
If you're experiencing a 404 error when switching to the Hungarian language for a product category URL on your site, it might be due to incomplete translations in the WPML settings.
Solution:

1. Navigate to WPML → Taxonomy Translation → Product Categories.
2. Check if all fields are properly filled in for Translations of taxonomy Category labels and slug, including the Plural translation field.
