Question: Why am I not able to edit the publishing name for Homepage (media id: 5) and Intranet (media id: 6)?
Answer: These medias are system defined medias and where the names Homepage and Intranet are shown throughout in system in texts, documentation, statistics etc. Also, these names have local translations to all languages supported. Therefore it’s not recommended to change the name for these medias.
If your company still would want to update the name then please contact our support. System can’t have translations to different languages when it is not a system defined media, so if you would like to re-name one of these medias then it will be the same name for all languages shown in system.
