Site Editor: The static homepage with the Front Page template that doesn't have the post content displays nothing

[arthur791004]

Description

Referring to Automattic/wp-calypso#79224, the site editor might display nothing when

1. The “Your homepage displays” setting is configured to a static page
2. The theme has a front-page.html or the user created a front-page template
3. The front-page template contains only patterns

The reason is the registered patterns/blocks are filtered out via the canInsertBlockType function because the block editing mode is disabled, and it's disabled due to useDisableNonPageContentBlocks

Step-by-step reproduction instructions

1. Install and activate the themes below

• Kigen
• Hey

3. Go to Settings > Reading, and configure “Your homepage displays” to a static page
4. Go to Appearance > Editor
5. Ensure the preview displays nothing

I think this was fixed in #53169. The fix will ship with Gutenberg 16.4.

This seems to match what was reported here by @wpsoul #52388 (comment)

Install and activate the Kigen theme

@arthur791004 that theme doesn't seem to be available in the WP theme directory. Could you share it as a zipped folder or, alternatively, point to a publicly accessible theme where the issue can be reproduced? You could also create a dummy theme with just the minimal code required to reproduce.

I guess it's slightly different since I tested it using the latest trunk yesterday and the issue is still there 🤔

Thanks!

I can't reproduce the issue on the latest Gutenberg trunk or on WP 6.3 RC3 with the Kigen theme:

Could you try testing also on WP 6.3 RC without Gutenberg enabled?

I tried again and it works now.

• With Gutenberg 16.3.0, the site editor displays nothing
• With Gutenberg built from the latest trunk, the site editor displays it correctly!

So, I expect this issue would be resolved with Gutenberg 16.4.0 🎉

Thanks for checking! Closing as fixed by #53169.
