Problem: The client is experiencing a fatal error on translated pages with the message:
Fatal error: Uncaught Error: Call to a member function get_requested_lang() on null
. Solution: If you're experiencing this issue, we recommend you try the following steps to isolate the cause: 1. Ensure you have a complete backup of your site for safety reasons. 2. Deactivate all plugins except for WPML. 3. Switch to a default WordPress theme, such as Twenty Twenty-One. 4. If the issue resolves, reactivate each plugin one by one to identify the one causing the conflict.
Problem:
I would like to use Rest API with WPML to manage posts / pages Solution:
Creating post and page translation using Rest API is not tightly integrated with WPML yet, You can use language parameter to create translation (?lang=fr) however it will still need some custom work to connect the translation with the original content of the post / page.
There is a workaround but you need to implement it . A wpml user shared this before sometime ago, other users reported that is working great, but have in mind that this is not coming from WPML so we cannot support it:
---------------
Finally i created a custom endpoint to link the 2 translations.
So the process is :
1- create the first post in language 1 (classic API POST call)
2- create the second post in language 2 (classic API POST call)
3- link both (custom endpoint)
