Howdy!
When did you first notice that? Was there a recent update to a plugin or theme or even core? Does it happen on all browsers? Or in a private tab?
I first noticed this in 2022, in August. There have been several updates since then, both plugins and theme, even WordPress has had two updates since then.
I read on a website that it is possible that some plugin has changed the permissions of the page, the problem is that I don’t know how to check this. I uninstalled all the plugins, changed the theme, but to no avail.
Oh okay. Are you able to post the plugins currently installed and active on the site?
I’m more-less wondering if that could be tracked down that way and see if I could replicate it or somebody else could as well.
I have an SEO plugin, Sitekit, a social sharing plugin and a security plugin.
I temporarily installed the classic editor and everything is fine there, all authors appear, but I prefer the current editor – Gutenberg, I got used to it.
Hi, Daniel. Do you happen to have a lot of users (more than say 10,000) on this site.
A recent update to WP added a “wp_is_large_user_count” flag, which when set (I think automatically based on how many users are on the site) changes some things to avoid big, slow, expensive user queries. One of those is populating the author dropdown on posts.
I’ve found on some of my sites, when I just wait around for a minute or so, the author dropdown pops up.
However, we have users on our site who just never see the dropdown, no matter how long they wait. And I haven’t looked into it recently (the team is bugging me again), but I believe there was a trac ticket related to a bug here around this.
So try waiting (you probably did, but I had to wait about 60+ seconds for reals).
You can also look into the https://developer.wordpress.org/reference/functions/wp_is_large_user_count/ function/filter. Sometimes changing that filter can fix this, but it also can cause performance issues on slow hosts.
Or try to trac down that bug if you’re up for it. Good luck.
