Problem: The client is experiencing issues with translating LearnDash courses using WPML on a site using the Kadence theme with Gutenberg. Specifically, when translating courses, the English versions lose their assigned lessons/topics/quizzes after saving, creating duplicate lessons and displaying 'trashed' lesson URLs in the Advanced Translation Editor. The course builder also reverts to an empty state, and the internal structure is lost on every save. Solution: We found that the client had not followed the correct procedures for translating LearnDash courses with WPML. Here are the steps to correctly translate LearnDash elements: 1. Ensure that lessons and quizzes are added in the builder tab for the translated courses. 2. Manually translate questions and add answers directly in the translated question screens. 3. Use the Translation Dashboard of WPML with the Advanced Translation Editor to translate courses, lessons, quizzes, and questions. For more details, refer to our guide on translating answers and building courses. Note that trashed lessons and quizzes appearing is a LeanDash behavior and not related to WPML. If you do not want these items to appear, they must be permanently deleted from the trash section.
If this solution does not resolve your issue or seems outdated, please check related known issues at https://wpml.org/known-issues/, verify the version of the permanent fix, and confirm that you have installed the latest versions of themes and plugins. We highly recommend opening a new support ticket if the problem persists. For further assistance, you can also visit our support forum at WPML support forum.
