Since WP 6.0 the Author dropdown field disappeared from the quick edit screen

Since the last update the quick edit author field does not appear anymore.

I've been trying my website in troubleshooting with default theme and no plugins, I tried to use the Capabilities (from Publishpress) plugin to restore default WP permissions and roles but nothing does the job.

For context I'm working on a website with more than 11700 users (and growing), among which there are 5 admins, 3 editors, 300 authors.

Another probably related issue: the /users.php page does not display the number of users for each role anymore. I can only see them next to the page selector "11 700 items"

This is expected behaviour due to changes made to improve performance on large sites (more than 10,000 users).

Hello @julianoe, welcome to WordPress Trac!

Thanks for the report. Since WordPress 6.0 the concept of "large sites" was applied to single sites too. Which means if the site has more than 10,000 users some elements which are known to cause performance issues are disabled. You can find more information on this in a ​dev note on make/core.

To change the threshold you can use the ​wp_is_large_user_count filter. Example:

add_filter( 'wp_is_large_user_count', '__return_false' );

Thanks for the info. I did not see the 10,000 figure was the treshold while skimming through the update logs. Our website passed it in the same week the update was pushed, hence the suprise.
We have updated it. Thanks for taking the time!
