Really helpful guide! Solved my issue quickly.
Glad it worked for you!
This article saved my project. I had a Divi child theme that kept breaking every time I updated the parent theme. The issue was exactly what you described — I was overriding functions.php incorrectly instead of using hooks. Switched to the hook method and updates work smoothly now.
Happy to hear it! The hook-based approach is always safer than direct function overrides. Divi’s parent theme changes frequently, so using add_filter and add_action in your child theme’s functions.php keeps your customizations update-proof. Glad you got it sorted!
We had the exact same Elementor + WPML conflict you described. Translated pages were losing their Elementor data during sync. Your fix of re-syncing the Elementor _data post meta worked perfectly. This should be in the official WPML documentation!
The Elementor + WPML combo is notorious for this! The core issue is that WPML doesn’t always copy Elementor’s serialized data correctly during translation sync. Glad the post meta re-sync approach worked for you. If you need ongoing stability, consider using Elementor’s built-in translation features instead of WPML for page-builder content.
