Error code 404

Hi In the widget under 404 Page Not Found Content, I inserted a page with the EW Pages widget. My expectation now, if an error occurs, is that this page is displayed. However, this is not the case, only the link that leads to this page is shown. Can this be changed so that it directly displays my page? Thank you Dan for the help. regards Heinz https://www.speiser-beschriftungen.ch
