Problem:
The client needs to configure WPML for a multilingual website with specific requirements: Belgium Dutch and Belgium French should appear in directories (example.be/nl and example.be/fr), while France French should be on a separate domain (example.fr). However, WPML does not support using 'Different languages in directories' and 'A different domain per language' simultaneously.
Solution:
We recommend using only the 'different domain per language' option. Configure your site as follows:
- example.be (for Belgium French)
- nl.example.be (for Belgium Dutch)
- fr.example.be (for France French)
This setup uses different subdomains for each language under the same main domain, aligning with WPML's capabilities. For detailed guidance on setting up different domains per language, please refer to our documentation here: https://wpml.org/documentation/getting-started-guide/language-setup/language-url-options/how-to-use-wpml-with-different-domains-per-language

If this solution does not apply to your case, or if it seems outdated, we highly recommend checking related known issues at https://wpml.org/known-issues/, verifying the version of the permanent fix, and confirming that you have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.
