Uncaught TypeError: Cannot read property 'replace' of undefined

Hallo,

Wenn ich versuche die Blogseite zu editieren, bekomme ich folgende Fehlermeldungen in der Console. Außerdem lässt sich der avia Editor nicht nutzen und dass nur auf dieser einen Seite. Alle anderen Seiten funktionieren einwandfrei. Plugins habe ich bereits alle ohne Erfolg deaktiviert. Ich bekomme auf der Blogseite nur das Ladesymbol:
