Hi guys,   I need a bit of help because I cannot figure out what's happens on a QuickApp I'm running on my HC3.   the QuickApp is Zigbee2mqtt available at this link:     Now the QuickApp is working fine. UI is available and everything is working properly.   As soon as I edit any line of code, a simple space in a line commented, then the UI became gray and unusable.   Here below the working UI   Please login or register to see this image. /
