Gutenberg 2.8
Gutenberg has been installed and running on our Dev and Prod servers for over 6 months now. I have just discovered that Gutenberg no longer works on the Prod server. It works fine on the Dev server however, which is an almost identical build.
The problem is the oft-reported stuck on "Loading" issue when you try to add or edit Gutenberg content. This has happened to us in the past, and a quick search through the forum resulted in a fix by disabling "Aggregate JavaScript files". However, this time we still get the hanging with aggregation disabled. I have also tried re-enabling JS aggregation, restarting Apache, rebooting the server, re-building the cache, all to no effect.
I can find no helpful information in the Drupal or the server logs. Is there any way of finding out what is happening here?
