[Solved] Why are commenter IP addresses suddenly missing?

Aaargh, it's enforced 'privacy' in WP core. That makes me sick. I MUST know and identify trolls.

FIX it by adding this to your theme's functions.php file. It will ADD a column with the IP.:

// 1. Add the column header
add_filter( 'manage_edit-comments_columns', function( $columns ) {
// Insert right after the "Author" column
$new = array();
foreach ( $columns as $key => $title ) {
$new[ $key ] = $title;
if ( 'author' === $key ) {
$new['comment_ip'] = 'IP Address';
}
}
return $new;
} );

// 2. Fill the column
add_action( 'manage_comments_custom_column', function( $column, $comment_id ) {
if ( 'comment_ip' !== $column ) {
return;
}
$comment = get_comment( $comment_id );
$ip = $comment->comment_author_IP ?? '';

echo $ip ? esc_html( $ip ) : '<span style="color:#aaa;">—</span>';
}, 10, 2 );

Thank you for letting us know. Glad to hear that the issue is solved.
