Hi Michael,
Thank you for your quick reply! Setting “Has archive” results indeed to an archive page, but having a page with the same URL as the CPT doesn’t result in a customizable page.
However, if I’m adjusting the “Cases Archivepage” in the Theme Builder it’s possible to customize the page.
Now it works, thanks a lot. Keep up the great work!
I still haven’t figured this out…
Have already contacted Divi support, but they say I need to contact Polylang support for this issue.
