Overview of the issue
When using Mollie Payments for WooCommerce with WPML, you might experience the following issue: the Voucher payment method appears on the original language’s checkout page but is missing from checkout pages in translated languages.
Workaround
To be eligible for vouchers, products must be part of specific voucher categories. See their documentation.
- Go to "WPML > Settings > Custom Fields Translation"
- Click on "Show system fields"
- Search for
_mollie_voucher_category, set the translation preference to "Copy" and save. - You might need to resave your original product to sync the field
