I have given my contributor role the file_upload capability. That role can now upload files, which is good and the purpose of me doing this. There is one issue though. When this capability is given they can also edit others media by going to the Media Library tab in the pop up from a post edit screen. They click show and then can edit the title or other meta info and click save all changes. How do I get rid of this functionality? How do I limit the media that this role can see in the media library to their own files?
