I think you have to delete the old one and add a new one. You should have a similar menu once your attachment is there (see attach.png).
There is no attachment permission per forum, it goes by usertype, and you can definitely upload one seeing your 1st post.
Edit: The remove attachment pop-up is buggy, you'll only see "yes" or "no" on the screen. I need to fix this..
