Value in [] cannot be blank.

Hi, I have a rather unusual problem for me that I can’t debug. Why so and, how to fix it. Maybe someone will have some suggestions.

Issue desc.
When I create a new post or sub-page. I fill in the title - add content and can’t save it. The button does not appear.

When I press “Ctrl + S” I get a message at the top of the page in a red box “Validation error, cannot save post. Value in [] cannot be blank.”
