Iframe code does find media files (when not logged into WordPress)

If a certain episode is embedded on other sites via the iframe code from the share menue the embedded player does NOT find the corresponding media files.
Fehlende Medien Dateien

Die zur Verfügung gestellte Konfiguration ist fehlerhaft. Ohne Mediendateien kann der Player nichts abspielen.

The src string alone also raises the same error message.


It happens also on my own site on a test page if I’m not logged into the WP backend.

The player itself on ordinary episode pages is ok, independently on the login status.

Any idea on that?

Edit: forgot the NOT in the very first sentence.


my guess is that the API calls from the player are blocked. Do you have any “security” plugins installed that disable unauthenticated API requests?

Thanks for replying.

Yes, I do use a security plugin but I’m not blocking (REST) API calls. A deactivation of the plugin also made no difference.

It seems to work for me:

Yes, on my own site it’s fine. But the iframe scr string in the share field is failing on other people’s sites

But chance I came across another plugin in use that barely disabled al API calls. After enabling the ones for web player shortcode everything looks good so far.

Many thanks for your hint!

i have the same problem.
The function for the iframe cannot load the data by the player.

Error message:

code	   "restx_logged_out"
message	"Sorry, you must be logged in to make a request."
status	401

Webpage ist: https://podcast.heagmobilo.de

iframe code:

<iframe title="Podlove Web Player: Wenn möglich, bitte wenden! - Night-Heiner im HeinerLiner" height="200" src="https://podcast.heagmobilo.de/wp-content/plugins/podlove-web-player/web-player/share.html?config=https%3A%2F%2Fpodcast.heagmobilo.de%2Fwp-json%2Fpodlove-web-player%2Fshortcode%2Fconfig%2Fdefault%2Ftheme%2Fdefault&episode=https%3A%2F%2Fpodcast.heagmobilo.de%2Fwp-json%2Fpodlove-web-player%2Fshortcode%2Fpublisher%2F103" frameborder="0" scrolling="no" tabindex="0"></iframe>

We are using Wordpress 5.8.1 with

  • Disable “BIG image” Threshold 1.0
  • Podlove Podcast Publisher 3.6.0
  • Podlove Web Player 5.4.13
  • Shariff Wrapper 4.6.7
  • Wordfence Security 7.5.5
  • WP Mail SMTP 3.0.3
  • WP Test Email 1.1.4
  • WPForms Lite 1.6.9

I have already looked through everything and deactivated plugins as a test, but so far I have had no luck.
Any hint is welcome!

Where or how can I check whether the API Calls has been switched off?

Thank you for your help.

I have found the solution to my problem and if, like me, you have found this forum looking for a solution, I would like to present it to you!
Because nothing is worse than always reading the answer “it works”, but never the solution itself!

Take a look at the THEME you are using. There in the directory under /wp-content/theme/… is a file named functions.php, search there for a part of the error text you get and deactivate this sub-function.

Try the internet search with this keywords: wordpress restx_logged_out error functions.php (for me, first german site helped me!)

Hopefully I could help you with your problem!
