User can’t upload images

Hi,

I’ve just installed this plugin on a site. I’ve created a specific role, ED Writer, and I want a user in that role to be able to create and edit posts – including uploading media to those posts – but not to be able to publish those posts or edit others posts.

Users are submitting posts via a CRED form which I’ve created using Toolset Access.

I’ve given the role these permissions:
create_posts
edit_media_s
edit_others_media_s
edit_posts
edit_private_media_s
edit_published_media_s
publish_media_s
read_private_media_s
unfiltered_upload
upload_files

But when they are creating a post and try to upload media in the edit pane via the Cred form, they get the following error message:
“You don’t have permission to attach files to this post.”

Are there any further permissions I need to grant to enable them to upload images into the post body?

Thanks!

Hannah
