How to get back WordPress’ native absolute path behaviour…

Dear Steve,
Thanks. Here’s the thing. I have had a plugin many months back when I switched from http to https, but it was uninstalled long time ago. There are currently no plugins and no theme that should cause this.

Moreover, WordPress and my Theme have had several updates over the past few months, meaning that it should either be in my child theme, or in the plugins. But nothing should logically do that.

Could there be a reason for plugins to change the behaviour, e.g. would it support a certain functionality? I am just trying to reason the other way around here.

Thanks

Nope, not just old links. If I look in my media folder, I can see that all files uploaded – even today – are displayed with a relative path only. If I look into the source when visiting my page, all images have relative links in the source code.

I am very positive it is something that is currently active.

Guess the only way to troubleshoot is switching off all plugins and adding them one by one…which is so tedious to do…

Thanks Steve,
I think I have found the issue, it was in my wp-config.php.
There was an entry that said:

define(‘WP_CONTENT_URL’, ‘/wp-content’);

I have changed it to:
define(‘WP_CONTENT_URL’, ‘https://mydomain.com/wp-content’);

Which seems to add back the domain in all links.

What are your thoughts?

Thanks for that, and for your support. It definitely has been a learning curve today. Truly appreciate your time and making me think into the right direction.

Cheers
