No more post thumbnails?

I can confirm this also – “Featured Image” panel in righthand sidebar (normally in between “Categories” and “Excerpt”) is not present.

To be clear – the option to set a featured image while editing a post (using the block editor not classic) has disappeared? This is definitely not intentional, but not something that we’ve seen during testing. A few testing questions:

– What version of WordPress are you on?
– Are you using a child theme? If so which child theme and is it possible to test activating ONLY the parent theme to see if the issue continues?
– Can you try disabling each plugin one-by-one to determine if there’s a plugin conflict?

Okay:

WP 6.1.1
Tested with all plugins disabled

1) Twenty Twenty-One theme activated
2) Understrap base theme activated (child theme not active theme)

Great! We’re tracking the issue on our Github account as well and think we may have a fix but will be doing some additional research before deploying a bugfix release. You can always manually swap out this line of code for the time being and see if it helps”

The updated code in inc/setup.php:

Yes, that line of code sorts things!

Great! We’ve released an updated (1.2.1) with the hotfix. Thanks for the help here.
