What permissions does a role need for the user to be assigned as the author of a post?
I have a Wordpress site with custom roles (except for administrator) and now wanted to create a role so that a user with this role can be manually assigned as the author of a post. I thus created a role which had all permissions checked in the "post" submenu, but none in the others (since this role is only there for this reason). A user that has this role assigned can now however still not be chosen as the author of a post, but only the ones with an administrator role. My question therefore is:
What permissions does a role need so that the user can be assigned as the author of a post? I would really like to not make this user an administrator
