guid isPermaLink is wrong

GUID’s are set by WordPress. WordPress, when you create blog posts individually, does not generate the same GUID for different posts. The actual guid value is created once though, and stored in the posts table.

My only guess is that the posts were imported from some other platform, the link/guid of the previous source were pointing to the same URLs.

Some other things: someone modified the wordpress posts database table, or a theme/plugin is modifying the guid in some way.

Here’s some instructions how to diagnose if it is a theme/plugin issue: https://create.blubrry.com/resources/powerpress/using-powerpress/diagnosing-feed-andor-player-issues-with-powerpress/

Angelo Mandato thank you for your answer. The posts are not imported, the posts are normally created direct in wordpress. We have also deactivated all plugins and used the standard theme. But it doesn’t work. Have you got any idea what is wrong?

I only see two guid’s in your feed, and they are now unique. Did you figure out the problem?

I have changed the guids manually. I haven’t found the problem till now.

All good now?

The GUIDs which we updated manually worked.

But now we have published a new podcast (https://www.musical1.de/news/espen-nowacki-interview-musical1-podcast-3/) the GUID is again the following.
<guid isPermaLink=”false”>https://www.musical1.de/news//</guid&gt;

Have you got any idea what is generated wrong here?

We adapt with “add_rewrite_rules” the URLs in the blog.

Here you can find the code.

Did you know if we must change there something?

PowerPress does not do anything with GUID’s. You either have WordPress misconfigured (I doubt this), or you have a theme or plugin messing with them.

To confirm PowerPress is not at fault, you can create a blog post with PowerPress disabled, then load up your regular blog feed and see what the GUID is.
