@Michel_72, I'm still able to download 2.1.2 from the version history so I've made a test upgrading from 2.1.2 to the latest, the one in marketplace:
Updated. No error logged, except the one when I installed 2.1.2 on IPS 4.5 due to a change on ACP menu. The error goes away when the right version is used on 4.5, as shown in the video.
