Required Information Missing error

I’m getting the following error on the player:

The direct link to the MP3 file works in the browser. And Podlove even verified everything on the Episode page:

Website is:


this is a configuration problem in your wordpress instance. The player can’t fetch the configuration, for example: doesn’t resolve.

Is that a Permalinks issue or something deeper? Sorry, I don’t even know where to begin to fix this issue…

I realize you’re not WP support, but could you at least give me some keywords I could use to start searching their forums for the answer? Thanks!

Maybe @ericteubert could help?

Very strange, if I open the config file in a web browser it comes back empty. When I curl it from the command line, I get a correct result.

The main difference is that the browser request is with --compressed and that indeed does not work. Do you have any cache plugins or esoteric gzip configs that might interfere?

I found the following problem when we had the same problem/error message. It seams to be a programming error (bug) in the podlove player embed code generator. The episode portion is using an url that hasn’t been properly URL encoded. Ginving the player a URL with two question marks…

In our case the Podlove player renders the following embed code…

<iframe title="Podlove Web Player: Halbe Katoffl - Ep. 30: Dennis Laubhan (KAZ): Schulmobbing, Russendisko & Eisschnelllauf-Liebe | Sport-Edition" width="320" height="400" src="" frameborder="0" scrolling="no" tabindex="0"></iframe>

This portion …

Should actually look like this …

Update with screenshot:

I fixed this behaviour in the latest version of the Webplayer.

So when can we update? We are running Podlove Podcast Publisher Version 2.8.6.
It needs to be merged into that branch/build, right? Any estimates on that?

It is within the 4.5.x release of Webplayer, available via CDN

Okay but we only had said plugin installed and the player seams to be part of the publisher? How do we side load the player from the CDN?
Will the publisher plugin package eventually be updated an we just need to wait?

Thank you for any hint.

You can switch between CDN and integrated player version in the “Modules” page of Podlove Publisher.

Thank you. That fixed it!

The sharing is now broken again! Our partner using the iFrame embed is not seeing the player anymore! The version we have is Podlove Podcast Publisher 2.8.7 and the CDN Podlove Web Player. It now doesn’t suddently render anymore.

See (right sidebar and error logs on that page):

Error logs are vast on the partner page… works on our page. We haven’t changed anything?

We are experiencing the same issue. Files will not verify. Have not changed anything. It was working last weekend when we uploaded out last podcast entry.

A bug in the player, I will update the Publisher as soon as the player fix is available.

tks, I’m anxious for the bug fix.

Podlove Publisher 2.8.9 includes the fix.

are there any plans to release this update?


guys, the error still persists.

in this post there is a way to do a by-pass to solve the problem.

however, the question remains: is there any prediction for the bug fix?
