[Résolu] Erreur avec Advanced Posts widget et WPML – "A non-numeric value encountered" in bfi-thumb.php

Problem:
The client is experiencing PHP errors with the Advanced Posts widget from PowerPack on their multilingual WordPress site using WPML. The errors occur only in the German version, suggesting an issue related to WPML.
Solution:
We confirmed that PowerPack Lite for Elementor is compatible with WPML and there are no reported issues currently. We asked the client if the issue appeared after updating WPML to version 4.7.3 and whether the problem persists if the German page is retranslated from scratch. We also provided a sandbox environment for the client to replicate the issue by following these steps:
1. Access the provided sandbox link.
2. Download and activate PowerPack Lite for Elementor.
3. Create a page using the Advanced Posts widget.
4. Translate the page and save the changes.
We asked the client to check if the problem reoccurs in this controlled environment.

If this solution does not resolve the issue or seems irrelevant due to being outdated or not applicable to your case, we recommend opening a new support ticket.
