We did not change things, but all of a sudden get this message:

I also have the page uddannelseslederne.dk that does not have the error, but almost identical setup??
Can you help?
Kindly Jesper
Found it myself. It was the plugin. WP Hide Post that caused the problem. Probably after PHP 7,1 update on webhotel.
