I've been using Upfront to customise Spirit for a couple of days on a local development set-up with Vagrant/VVV.
Today, I get a white page next to the Upfront editor sidebar. I tried to restart vagrant and the browsers (Mac Chrome, Firefox). I tried to choose the home page using the page button in the Upfront editing sidebar. Nothing has worked.
The home page (the only page I've worked on so far) looks fine, except a region near the bottom of the page that should have a Google Map is blank.
I believe I'm running the current version, but I don't recall if this started immediately after I updated. I don't think it did.
Any ideas for fixing Upfront?
