Hy, I`m searching this for a while.
So my add media button is not showing when non log in user want to post a image ( it is showing in admin, log in user view).
I read all the topics, try everything but nothing.
I can use featured image, attachments but they are only showing in posts,
in my custom post type (where my content goes) i can only see text with no image.( and yes my custom post type is checked) And also it would be a lot easier to do it with add media button.
