As soon as I try to disable the Dashboard for Authors, I can no longer login as an Author. I get this error message: You do not have sufficient permissions to access this page. It works fine for Administrators and Editors. In addition, even if I enable Dashboard, there are other errors as an Author. I can't get the pages to show up. All the other items seem to work fine (posts, media, links) but I have pages enabled and they don't show up. Again this is only for Authors.
