Problem: You are experiencing an issue where featured images disappear on pages translated into secondary languages. This problem is also visible in the WordPress editor view for the translated page. Solution: We found that in WPML → Settings, the Media (attachment) option was set to 'Not Translatable', which hid the media translation option and did not duplicate the media attachments. We recommend changing this setting to 'Translatable'. After making this change, run the media duplication option in WPML. This action will duplicate the missing images for the translations by creating an entry in the database that links the original image to the translations, without physically duplicating any images on the server.
If this solution does not resolve your issue, or if it seems outdated or irrelevant to your case, we highly recommend checking related known issues at https://wpml.org/known-issues/, verifying the version of the permanent fix,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 the problem persists, please open a new support ticket.
