[Resolved] how to change in quick edit few posts the lang?

Problem:
You are looking to change the language of multiple posts quickly using the quick edit feature.
Solution:
We currently do not have a quick edit option to change the language of posts directly. If you need to manually assign a source language or connect translations manually, we recommend following this guide: https://wpml.org/faq/how-to-link-already-translated-pages/

If this solution does not apply to your case, or if it seems outdated, please open a new support ticket. We also highly recommend checking related known issues at https://wpml.org/known-issues/, verifying the version of the permanent fix, and confirming that you have installed the latest versions of themes and plugins. For further assistance, you can always contact us through our support forum.
