[Risolto] My Danish page has been

Background of the issue:
I was trying to make changes on a couple of pages in the main language Danish and then use the Advanced Translator for the English translation. A couple of minutes before, I had used the Advanced Translation on an Elementor template with no problem. The issue can be seen at link nascosto.

Symptoms:
The Advanced Translator jumped from English to Danish, only showing the title. I can't access the Advanced Translator on pages at all.

Questions:
Why is the Advanced Translator jumping from English to Danish?
Why can't I access the Advanced Translator on pages?
