I have yet to get oAuth callbacks to work properly. After clicking Allow, I end up on a completely blank twittter.com/oauth/authorize page. If I try to look at the source, it asked if should resend. If I do, the source comes back that contains the redirect. But if I'm not looking at the source, the page just hangs for a while, and then ends up blank.
What is up here? I've tried a variety of callback urls, from localhost, to the actual domain I'm using for development. Any one experience similar?
