A quick check learned that the plugin WP REST API Controller was the problem.
We disabled the plugin and know it works.

Many thanks!

Thanks for your reaction!

I checked the options, but ‘categories’ is not available in the document panels sections.
Something is wrong indeed. Could it be another plugin? Anyway, we will test it by deactivating the other plugins…

Thanks in advance!

You mean this?
