Problem: The client needs assistance making the Divi module link URL translatable or linking to its translated pages. The URL does not appear in the WPML Advanced Translation Editor, and there is no option to automatically translate or sync it to its translated page. Solution: If you're experiencing this issue, we recommend searching and translating the link as explained in the following documentation: Translating Links with Advanced Translation Editor. For links to be automatically adjusted to translated ones, they need to be full HTTPS links, and the Divi modules need to be compatible. If you are using third-party Divi modules, they might require additional XML configuration. Please check the following documentation for maintaining Divi Builder compatibility with WPML: Maintaining Divi Builder Compatibility with WPML.
