Problem:
The client is experiencing an issue where courses can be published without filling in all required fields when WPML is enabled. This problem does not occur when WPML is disabled.
Solution:
We recommend updating Advanced Custom Fields (ACF) to the latest version as a similar issue with field validation was resolved in that update. You can find more information on this update here: Advanced Custom Fields conflicts with field validation on AJAX requests.
Additionally, it is not necessary to translate custom fields groups with ACFML. Therefore, you can set ACF custom fields to be not-translatable in WPML->Settings->Post types translations, which allows you to manage fields from one place rather than two. For more details on managing ACF with WPML, visit: Translate sites built with ACF.

If this solution does not resolve your issue or seems irrelevant due to being outdated or not applicable to your case, we highly recommend checking related known issues at https://wpml.org/known-issues/, verifying the version of the permanent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. If further assistance is needed, please open a new support ticket at WPML support forum.
