Hi,

Our second-tier supporter has let me know that our developers are already working on WPML compatibility with PHP 8.4. Among other things, those deprecation notices will also be handled. It will be included in future versions of WPML. We'll keep you updated when the version with the fix is released. Unfurtunatly I can't provide an ETA for when it will be released.

I appreciate your patience.
Itamar.
