I'm using the latest version of Podpress (18.104.22.168) on the latest version of WordPress (3.3.2).
While submitting a new podcast to iTunes, I get the following error: "Your episodes are hosted on a server which doesn't support byte-range requests. Enable byte-range requests and try your submission again."
I've successfully submitted other feeds from the same multi-site WP installation and it has always worked without this error.
My hosting provider says:
It seems like an issue with WordPress/Apple. From what I gather, Apple
may have changed how they accept itunes submissions, and the issue is
that when the customer submits their podcast it's being handled by
WordPress (perhaps rewritten or given a clean URL) instead of just going directly to the filename on the server. That routing through WordPress is causing the failure. So yeah, you may need to make some changes to your feed so that it will link directly to the file... apache itself should handle byte-range just fine.
