Das Update auf 2.9.0.beta5 verursacht ein Problem mit meinem Dashboard-Plugin. Etwas löst einen Fehler in einer Ansicht des Plugins aus:

Dies scheint nur in der Index-Ansicht meines Plugins aufzutreten, nicht auf anderen Seiten des Plugins oder in Discourse. Ich bin mir nicht sicher, wo ich suchen soll. Ich bin froh, dass ich das Upgrade zuerst auf meiner Staging-Site durchgeführt habe!

Das Obige deutete für mich darauf hin, dass dies mit dem Chat-Plugin zu tun hat, aber es tritt auf meiner Dev-Instanz auf, ohne dass Chat installiert ist.

Wow, und wenn ich Google nach `ActiveSupport::MessageEncryptor::InvalidMessage "fast_attributes"` durchsuche, gibt es nur dieses Thema!
