I have a layout element that outputs the featured image on each page. Since upgrading to WordPress 6.2, all the content below the featured image disappears (it’s not in the DOM). As soon as I deactivate the element or deactivate GP Premium, the content is loaded again. I posted a video in the private information field as I upgraded to 6.2 only locally.
OK – update.
We tracked it down to an issue with the core Post Featured Image block that you’re using.
Can you replace that block in the element with a GenerateBlocks Image Block, and you can set its Dynamic Data options in the sidebar to show the Content Source > Featured Image.
Replacing the block with a GenerateBlock would of course be an option, however this multisite does not have GeneratebBlocks installed and the Featured Image would be the only case why I would install the plugin.
I’ll stick with the “manual” PHP solution for now and include the featured image as a template part via the generate_after_header hook.
