Background of the issue:
I am trying to modify the global footer of the German language version of my site, hidden link, using WPML with the Divi theme. I have deactivated all plugins except WPML, but the issue persists.
Symptoms:
A popup appears saying that there is an error when I try to modify the header of the German language.
Questions:
Why does an error popup appear when modifying the German header?
Is there a compatibility issue between WPML and the Divi theme?
