When an author tries to edit a page on the frontend (it's using a CRED FORM for frontend page editing that I made), they can just fine. Then they press the INSERT MEDIA button and try to upload an image. It gives an error back "Sorry, you are not allowed to attach files to this post." Basically it won't let them upload anything.
In ACCESS, which is activated, I have authors set so they can upload files. What else can I try? Everyone else in user groups above them can upload images just fine.
I appreciate your help but what you are saying isn't making sense... that's why I keep asking. It's very vague. You now said the media type should have the same permissions but they are using the permissions from the default post type, which I changed. That change had no affect anything.
