Hallo wir haben seit kurzem das Problem, dass in unserem Shop weder im Frontend noch im Backand die Kategorien oder Artikel aufgerufen werden können. Beim klicken auf Artikel im Backend erhalten wir folgende Meldung :
Ups! Ein Fehler ist aufgetreten! Die nachfolgenden Hinweise sollten Ihnen weiterhelfen.

Hallo,
ansich steht doch die Fehlermeldung recht deutlich da: "Column not found: 1054 Unknown column 't0. **lenz\_background\_image\_url’** in ‘field list’. Es liegt also an einem Plugin vom Hersteller Lenz.
Beste Grüße
Sebastian
