Feed Don,t Update the new podcasts

Your feed has only three episodes in it, and these appear in the Store and when subscribing. Your linked page at

http://www.desvariosvarios.com/desvarios-con-cafe

has a fourth episode but this has not made it into the feed. There is no evidence of a fifth episode.

You have constructed your podcast in WordPress and I can't advise on what you should do to get the fourth episode into the feed. You may find this WordPress instructional page on podcasting helpful:https://en.support.wordpress.com/audio/podcasting/

You need to make sure you're entering the URL's of your media files into the Media URL field inside of the Podcast Episode box, then you should press the "verify media" link next to that. This will ensure that the media file is properly added to your podcast feed. You're using the PowerPress plugin and PowerPress won't add an entry to a feed unless it contains an enclosure.
