Authors suddenly can’t remove themselves from posts

Hi @alefnula,

Thanks for reaching out! Yes, that was introduced as a security measure to avoid any unprivileged author publishing content in the name of others. Latest release (4.7.10) includes a hook so you can bypass that constraint. Just add this snippet to the Custom PHP option in the Authors > Settings > Advanced screen (or any other place you prefer, like in your child theme’s functions.php file):

add_filter( 'authorship/post_as_other_author', '__return_true' );

That should do it!
