Hello Community
I got the same exact issue after upgrading from 2.0p20+ to latest 2.1
I’ve checked the user_dashboards.mk - I could not find any zero timerange " 'timerange': '0' ".
In my file : timerange are eather in seconds exp : 'timerange': 321654
or
explicit Hours or days like this : 'timerange': '25h' 'timerange': '35d'
