Problem: If you're experiencing issues where WPML deletes image files from the server, particularly large images that WordPress scales (creating a file with a -scaled suffix), here's what might be happening. This issue occurs when you upload a large image (over 2560px) to the default language, and either delete the image from a secondary language or remove a language from the settings screen, which also removes leftover content. This results in the deletion of generated media files from the server, breaking the media library in the default language. Solution: We recommend updating to WPML version 4.7.2 or later, as this issue has been addressed in these later versions. If you're still facing this problem after updating, it might be due to other factors. In such cases, please check the related known issues, verify the version of the permanent fix, and confirm that you have installed the latest versions of themes and plugins.
If the solution provided here does not resolve your issue or seems irrelevant, we highly recommend opening a new support ticket. You can do so by visiting the WPML support forum.
