Okay, I think I’m officially done with the update
The most challenging part was the SSL and media files
Inside the plugin there are several spots where you need to enter direct media URLs.
Even though original site had the SSL all media file links ended up converting from HTTPS to HTTP. Not totally sure why, but..
This made podcast inaccessible through iTunes, since it fetches media files directly from site.
Easy fix is to get “search and replace” plugin and adjust whole SQL DB (basically replace HTTP with HTTPS )
Hope this helps to all struggling podcasters out there!
