Are you Sure ?
a newer version #1821 of ALTUI is available, do you want to upgrade ?
which I of course answered with yes.
After that I’am stuck in a loop. Every time I reload the page the message pops up again.
The version displayed on the screen bottom is 1818, that’s what’s probably causing the message.
Also, my device page is completely messed up, see attached screenshot.
I tried reloading luup engine, clearing browser cache, reloading, to no avail.
