 I have a test site with which I wanted to start exploring the Gutenberg
 editor. Not having used it for quite a while, when I logged in I noticed
 there was an update to 3.8.0 available (I don't remember exactly what I
 was on previously, but I know this skipped a lot of previous updates).

 In submitting this ticket, I see "Version" shows the latest as 4.9.8 --
 why don't I see that when I update the Gutenberg plugin?

 When I go to edit a post (all of them on this test site were converted to
 Gutenberg), I just get a blank browser window (not just a delay before
 rendering, but a blank -- i.e. white -- window).

 If I use the browser's back button, but then select the Classic Editor, I
 get a dialog telling me this was edited with Gutenberg... with warnings.
 If I continue, all the content is there. If, instead, I select Gutenberg
 the blank window is displayed.

 Latest Firefox (62.0) under Linux Mint (18.2)
