Hi there, i am experiencing same problem on three xibo installation i now have tried.
Xibo 1.8.2 with docker toolbox on win7 pro (3 different pc’s)
I create a layout with one region and text “enter text here” save and schedule. and it gets published on the player…
If i then add some text to the layout or any other change then it does not get downloaded on the player.
auditing the player shows that the layout is invalid
Any suggestions? I will now try a win10 installation
