Problem: You want to translate post content but keep the post slug in the default language (English). Solution: We recommend following these steps: 1. Navigate to
WPML > Settings > Translate documents options
and enable Copy from original language if translation language uses encoded URLs. 2. Go to
WPML > Languages > Edit languages
, select Encode URLs: Yes. 3. Save all changes. 4. Edit a post, make a small change to the content, update it, and then translate it again. Check the translation post slug in the frontend. For more details, please read our documentation on translating page slugs: Translating Page Slugs Documentation.
If this solution does not apply to your case, or if it seems outdated, we highly recommend checking related known issues at https://wpml.org/known-issues/, verifying the version of the permanent fix, and confirming that you have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.
