Tried the 1 Click Update and it bombed.
on domain.com/admin/utlities/updates url I get
Twig Runtime Error – Twig_Error_Runtime
Variable "CraftPersonal" does not exist.
1. in /vendor/craftcms/cms/src/templates/_layouts/basecp.html
And then on the domain.com/admin/dashboard url:
Twig Runtime Error – Twig_Error_Runtime
Variable "CraftClient" does not exist.
1. in /vendor/craftcms/cms/src/templates/_components/widgets/RecentEntries/body.html
The CP is now unusuable
composer update
, it should bring you up to the latest version. – Lindsey D♦ Apr 5 '18 at 23:35
