I am having some issues using Role Scoper and the Flash Uploader in WordPress. I am attempting to give a user access to add an image to a custom post type. The user is set as an author for this custom post type, and as far as I can tell has complete access to everything within the custom post type. Under the 'RS Role Definitions' in the Role Options I am seeing that the Author role for that custom post type has the ability to upload files, but when the user goes to perform the upload they are given an error message that says 'You do not have permission to upload files.'
Please let me know if there is a setting that I am missing to give these users permission to upload files.
