I installed Ronald Heft's excellent Podcasting plugin about a month ago, and used it for a single audio file. Since then (if I recall the chronology properly), I've upgraded to WordPress 2.5.1. Today I was surprised to discover that the player on my single podcast episode thus far has gone missing -- the little Flash player doesn't show up at all. I've upgraded to Podcasting 1.64, the latest version, and that's made no difference.
As a test, I grabbed the output HTML for that blog entry and pared it down to the bare essentials, leaving the HTML structure, the player.js call in the header and the object/parameter tags in the body, but that didn't make any difference, so I think I can conclude that I'm not including any other code that's problematic.
Can anybody offer some guidance as to what might be going on here?
