wp-comments-post.php?for=jetpack 404 (Not Found)…

I released my website yesterday, moving WordPress up one folder from a dev directory.

(e.g from: /www/sitedir/devdir/ to: /www/sitedir/)

Everything is working great except comments. I get a 404 when submitting a comment.

I looked at the network traffic and discovered the 404 error:
www.u2act.com/devdir/funny-wpdir-name/wp-comments-post.php?for=jetpack 404 (Not Found).

The path should be:
www.u2act.com/funny-wpdir-name/wp-comments-post.php?for=jetpack

How can if fix the Jetpack comments config to use the correct path?

Thanks,
Chris
