Mollie Payment method called

This thread is resolved. Here is a description of the problem and solution.

Problem:
The client is unable to see the payment method 'Cheques' (known as 'Voucher' in English) in all languages on their WooCommerce site. This issue is specifically occurring on the checkout page, where the payment method appears only in French but not in Dutch or English.
Solution:
If you're experiencing this issue, we recommend you follow these steps to ensure the payment method appears in all languages:
1. Ensure you have a full backup of your website.
2. Navigate to WPML > Settings > Custom Fields Translation and click on Show system fields.
3. Locate the

_mollie_voucher_category

field and set it to Copy. Remember to save your changes.
4. Update your product in the original language and save to apply the new settings. You can edit a text and save as an example.
5. Re-save the translations.
This solution assumes that the original products have the 'Products voucher category' set, allowing the voucher values to be copied to the translations.

Please note that this solution might be outdated or not applicable to your specific case.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 issue persists, please open a new support ticket at WPML support forum.

francoisV-9	Background of the issue: I am trying to see the payment method called "Cheques" in every language on my website (this is a payment method (called "Voucher" in English from the plugin Mollie for WooCommerce). The issue can be seen on the checkout page: hidden link To be able to reproduce the issue, you have to add this product to your basket: hidden link Then on the checkout page (please select country = Belgium), you will see the last payment method called "Cheques" (see the attached screenshot) but if you switch to English or Dutch, this payment method does not appear (see the attached second screenshot). Symptoms: The payment method "Cheques" only appears in French and does not appear in other languages like Dutch and English. Questions: Why does the payment method "Cheques" not appear in Dutch and English? How can I make the payment method "Cheques" visible in all languages?

I've asked for you to install the Mollie plugin, so I could make further tests and verify compatibility. My reply was private, as it contains access data, so please make sure to check it in detail. Let me know.

francoisV-9	Dear Lucas, I did not see your private messages. I did what you asked on your sandbox. I added a product and installed the Mollie plugin but I can't find where the Shop is on your sandbox website so I can't test if I see "Vouchers" at the checkout. Also I can't find where to translate the product, it is not the same as in my WPML installation (there is no little pen to translate). I also found the strings to translate for the "Vouchers" and for the "Please try to translate this description" strings but I don't know how to translate them. It is not the same as in my WPML installation. Can you continue from here? Thank you in advance for your help.

Lucas Vidal de Andrade WPML Supporter since 11/2023 Languages: English (English ) Timezone: Europe/Vienna (GMT+02:00)	Hey there, I was able to find a solution. Please make sure to have a full website backup and follow the steps below: 1. Go to WPML > Settings > Custom Fields Translation and click on "Show system fields"; 2. Find the _mollie_voucher_category field and set it to "Copy". Save; 3. Update your product on the original language and save, so the new settings are applied. You can edit a text and save, for example; 4. Re-save the translations; Of course, the original products must have "Products voucher category" on it, so the voucher is available and the values are copied to the translations.

francoisV-9	Hi, Thank you for your help. I already made the 2 first steps before: 1. Go to WPML > Settings > Custom Fields Translation and click on "Show system fields"; 2. Find the _mollie_voucher_category field and set it to "Copy". Save; But I didn't know that I had to make an update/change on the product and to save (and then to re-save the translations) to be able to see the "voucher" payment method in the other languages. Now it finally works. But there is still something that I can't translate: the description of the "Cheques" payment method (see the attached screenshot where you can see the text "Test description"). I found the text "Test description" in the string translations (see attached screenshot) and I translated it (by "Test of an English description" in English) but the translation does not appear on the website (I see "test description" (which is the French text) in every language). How can I translate this? Thank you very much for your help.

I'll create a separate ticket for that, so we don't have the initial issue mixed with this one. I'll answer you directly there: https://wpml.org/forums/topic/split-mollie-voucher-description-translations/ Thank you.
