Craft 3.1: value of craft/web/Application::getIsLive() must be of type boolean, null returned I tried upgrading a Craft 3.0 installation to 3.1, and got the following error:


  "value of craft/web/Application::getIsLive() must be of type boolean, null returned"


Has anyone else run into this?  Does anyone know a fix?
I resolved this by adding 'isSystemLive' =&gt; true in general.php
