Itunes not recognizing my validated feed

kpurcell, what is your feed URL? It may not be the same issue.

The half baked solution for hot linking is to block links that do not have a referrer. I can tell you podcasting uses HTTP to transfer feeds and media files, but it does not use any web browser or link navigation, which means there is no Referrer data when feed / media URL requests are made. So if you have a solution that is preventing hot linking and you want to podcast, then you’re going to have to turn off the hot linking features, at least to where your media files and feed URL.

There are lots of other reasons for a feed not to work. Aggressive mod_security settings on the server or even a WP security plugin can prevent it from working correctly. If you share the URL I can look at it and tell you what the cause is.

kpurcell, if you were able to switch plugins in only 15 minute time period to fix the issue, then the issue was more than likely something to do with server caching than with any one plugin.
