Design>Widgets: Im Editor ist ein unerwarteter Fehler aufgetreten.

Seit kurzem tritt der genannte Fehler auf. Woran kann das liegen?
Der Fehler bleibt auch nach Widerherstellung von Sicherungen mit updraftplus bestehen. Ich kann es nicht 100% sicher sagen, aber habe das Gefühl, dass der Fehler vorher (also zur Zeit der Sicherung) noch nicht da war.
Hänge unten den Bericht aus Werkzeuge>Website-Zustand an.
Bin absoluter wordpress-Anfänger. Bitte sagen, falls ich noch weitere Infos hier bereitstellen kann.
