Known issue

Problem:
The client reported that activating the WPML plugin affects the Elementor page builder on their website. Specifically, some blocks drop, and custom CSS for the main menu does not appear.
Solution:
We recommended the client to first ensure that the issue is specifically related to WPML by deactivating all other plugins except for WPML and Elementor and then checking if the problem persists. This helps isolate the issue. Additionally, we asked the client to provide screenshots to better understand the specific problems they are facing.
We also inquired if the custom CSS might be causing the issue when WPML is activated and suggested testing the site without the custom CSS to see if that resolves the problem. Furthermore, we requested details on how the problematic sections were created to diagnose further.
