Problem:
An Elementor Custom Widget "Content Switcher" from "HappyAddons" is used to display different product collections in the form of sections for which an Elementor template is used.
The Elementor content is translated with the WPML Translation Editor.
On the translated content the translations do not show up as the Content Switcher Widget is not applying the correct template.
Solution:
Take note, that this is a compatibility issue between "HappyAddons" and WPML. The user was asked here to recreate the issue on a test so that we can escalate the problem internally and work on a solution.
Saldy the user did close the ticket before we were able to take any further steps.
If you have a similar issue, please open a ticket.
Workaround:
Make sure that you translated your Elementor Templates, then open Elementor on the translated content and make sure that the Content Switcher Widget is using the correct template.
Take note, that the settings of the widgets might get reverted, if you translate the content again with the WPML Translation Editor.
This means you should use the WordPress Editor as a translation method for affected content until we are able to find a solution for making the "Content Switcher Widget" translatable with the WPML Translation Editor.
