Problem:
We would like to translate the meta description with WPML but if we follow the Rank Math Guide: https://rankmath.com/kb/multilingual-seo-wpml/#num-11-3-how-to-translate-the-meta-description-or-titles-of-rank-math-plugin, we’re unable to translate the meta description and title. Are we doing something wrong?

Solution:
Please try the following steps:

1. Go to WPML > Settings > Custom Fields translation
2. Set the following fields to "Translate"

- rank_math_description
- rank_math_title

3. Edit the original post/page where you add the meta description
4. Make a small change and save it
5. Update the translation

Problem:

I cannot make an English/Japanese site on only the front page.
If I change anything on the front page in English, for example, the front page of Japanese also will be changed into English and vice versa.

Solution:

1- Go to WPML-> Theme and plugins localization, select your theme/plugin, and scan
2- Go to WPML-> String Translation
3- Scroll down and click on the "Translate texts in admin screens »" link
4- Search for the needed strings
5- Select the strings
6- Click on the "Add to String Translation" button
7- Then click on the "« Return to String Translation" link
8- Translate the strings, clear the cache, and check the front end

Problem:
I duplicated my products from a secondary language, this works great. But how do I duplicate the attributes of this products, so they appear also in this secondary language and not in my default language.
Solution:
we do not recommend duplicating from a secondary language, as this might cause unpredictable issues in the synchronization between languages.

This doesn't mean it is not possible, but rather tricky.

To duplicate a product correctly from a secondary language to third language, you could follow this thread : https://wpml.org/forums/topic/copy-duplicate-products-from-secondary-language-to-third-language/

But if this didn't solve the issue with attributes duplication, I would recommend duplicating the content from the default language > Translate that duplication

PS : If you are using the Advanced Translation Editor, you won't have to translate it from scratch, as this editor contains “translation memory” that saves your previous translations in a given language.

Problem:
I'm trying to figure out if there is a way to have both different domains per language AND a subdirectory per language for specific domain.

e.g.
example.com -> English version

test.com/es -> Spanish version
test.com/pt -> Portuguese version

Solution:
It's not possible to have a mix of domains and directories/parameters for your languages, please check here: https://wpml.org/documentation/getting-started-guide/language-setup/language-url-options/how-to-use-wpml-with-different-domains-per-language/#frequently-asked-questions

Instead, you can use a mix of domains/subdomains like the following:

example.com -> English version
test.com -> Spanish version
pt.example.com -> Portuguese version
