I've recently switched from Disqus to Jetpack comments. I'm coming across a problem that the comment form is redirecting to my blog's login page (wp-login.php).
When posting a comment, whether logged out or logged in via Twitter, Facebook, or WordPress, clicking Post Comment sends me to a blank page at http://jetpack.wordpress.com/jetpack-comment/ and hangs for several seconds. Then it redirects to http://www.sethmad.com/wp-login.php?redirect_to=http%3A%2F%2Fwww.sethmad.com%2Fwp-admin%2F&reauth=1 and demands login. (If I log in it takes me to the admin page, and the comment is lost.)
My discussion settings don't require registration. I can't figure it out. Any ideas? Blog URL is http://www.sethmad.com
