When trying to embed a podcast URL on WordPress, the following error message is presented: Your podcast couldn’t be embedded. Please double check your URL.
This error can be caused due to invalid characters presented within the .XML content parsed from the URL.
On your WordPress website, navigate to MySites > Settings > Writing and ensure that the podcast information doesn’t contain any special characters such as ‘&,£,$’. Remove/change any special characters and save changes before attempting to embed the URL again.
You can validate your URL here: https://www.castfeedvalidator.com/
You may have issues also adding your podcast to popular platforms such as Spotify until this issue is resolved.
