Update to 3.8.0 results in blank screen

[johngoold]

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)

Since Gutenberg is not in core, Trac is not the right place to report this problem.

Please use the plugin support forum or open an issue on the GitHub repository (links available in the plugin).

Hi @johngoold, welcome to WordPress Trac! Thank you for testing Gutenberg.

Until Gutenberg is merged into core, we're tracking its issues on GitHub: ​https://github.com/WordPress/gutenberg. Could you please report the issue there? Thanks again!

I have been tracking this issue and would like to learn more. If you are able to check Firefox > Tools > Web Developer > Web Console for errors, that would be helpful information to have when you post to ​https://github.com/WordPress/gutenberg/issues. There are a number of possible causes for a blank screen problem. In my experience so far, the most-likely culprits are: plugin or theme conflicts, strict security rules which block the API, and/or some other server configuration problem. Would be happy to look into the details with you on GitHub!
