@amg0, I am having issues with .js files from apps which were deleted and for which I delete files on vera units.
Somehow when ALTUI loads it is looking for the js files from these apps which are no longer on the unit. I am being forced to keep the .js files for them. I noticed in particular that the apps from Rigpapa have this problem. Both DeusExMachinaII and SiteSensor have been problematic for me. I try to keep my units clean and I sometimes move an app from one unit to another or to Openluup so when I delete an app, I delete all the files too. This prevents ALTUI from loading.
