Custom widget blocks created using ACF prevent the Widgets from being updated within the Dashboard. On save, a fatal error message is shown and the widget is moved to the Inactive Widgets section. Checking the logs, we see the error is in the WPML_Register_String_Filter->save_string first argument. Log output included below:

Bug confirmed by temporarily downgrading the environment to PHP 8.0, which resolved the error. Our host has scheduled the end of life for PHP 8.0 for all customers by the end of this month, so keeping it on that version is not a viable option.

Hi there,

WPML is not officially compatible with PHP 8.2 yet, and the issue is WordPress itself is not compatible with PHP 8.2 officially yet so it will take time for WordPress and WordPress plugins to adapt and finalize.

There is no ETA for a compatible release but our development team are working on a release.

Thank you.
