Comment:

 Before the update to WP5.1, in my case there was never an issue with file-
 sizes or time-outs. There was simply not enough time between adding the
 image/gallery block and the JSON error to be connected to a time-out.
 Also, all image files are below 1MB and on this host I have never had a
 problem before Wordpress 5/Gutenberg.

 After the update to WP5.1 I no longer see the JSON error, but updating
 posts that contain images or galleries still give the red **Updating
 failed** banner, while the post does get updated.

 Interestingly, I am also using the Meow Gallery Block plug-in and whether
 I use the media gallery OR an upload to add a gallery, the click here to
 refresh the preview shows no gallery in the editor. When using the
 standard Gallery Block, this does not happen.

 In both cases, although the red **Updating failed** banner shows, the post
 gets updated.

 Cutting around corners: I wonder if we are looking at a JSON issue ''or''
 a Gutenberg editor design flaw...

 To make things even more intriguing; I have copied my site in a VirtualBox
 / Turnkey appliance, using the same theme and the same plug-ins and never
 do I receive a JSON or Updating failed error, even though the Virtualbox
 (deliberately) allows for smaller uploads and has a lower memory limit.
 The Virtualbox has cUrl enabled, the live site hasn't, but as far as I
 know, that should not be an issue when editing posts - it never was...

 Live site: Ubuntu 16.04.1 / Apache 2.4.18 / PHP 7.0.33 / MySQL 5.7.25 / WP
 5.1
 Virtualbox: Debian 9.4 / Apache 2.4.25 / PHP 7.0.33 / MySQL 5.7.25 / WP
 5.1
