Problem: The client is trying to assign an English page to its Estonian version, but the Estonian page does not appear in the list. The client wants to avoid using the advanced translator and prefers to copy and paste the content in the WordPress editor and connect it as a translation, as it was possible in older versions of the plugin. Solution: We recommended following the instructions on how to link already translated pages, which can be found here: https://wpml.org/faq/how-to-link-already-translated-pages/. We also advised the client to ensure that the pages were created separately, each in its own language. To do this, switch the language from the top bar in the backend, navigate to "Pages", and create a new page in each language.
