Problem: You are trying to permanently delete images in all languages at once on your development site. You have discovered that the issue is related to the WPML plugin and are unable to synchronize images so that deleting and replacing an image in Italian also deletes and replaces it in English with the same name. Solution: Deleting images in one language does not delete them in another. Therefore, what you are asking for (deleting and replacing in Italian and simultaneously deleting and replacing in English) is not possible with WPML, as it does not create duplicate files but only new entries in the database. If you want to delete the files as well, you should first delete the media library in English and then the Italian one; this way, the files will also be deleted.
Please note that this solution might be irrelevant if it's outdated or not applicable to your case. 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. If this does not resolve your issue, please open a new support ticket at WPML support forum.
