I tried to use the apparently outdated plugin, Co-Auhors Plus, and that may have something to do with my issue, but I have no idea …
One of my authors has disappeared from the drop-down menu of “Authors” under the posts. She doesn’t appear in the “Quick Edit” Author drop-down either.
The strange thing is that she still appears as author of her published posts. But if I try to “edit” her posts and click on the Author drop-down, she’s not listed.
She is properly listed as a user/author in the network.
She is properly listed as a user/author on the site. I tried changing her role to she if that would help, but it hasn’t helped. (Didn’t try every role.)
