Attempt to read property “display_name” on bool

Hey @webmasterfreya,

Thank you for reaching out!

I notified our development team, and they investigated it right away. It seems that there is no failsafe on the presenter when there is no author present on the post or page. However, it’s safe to ignore the warning. The development team will make sure to create a fix in a future version to fix this.

for now I wrapped it in an if statement and the error went away, until the patch fixes it:

if ($user_data) {

    return \trim( $this->helpers->schema->html->smart_strip_tags( $user_data->display_name ) );

}

Hey @shev72,

If you have the same issue visually on your site, then I recommend disabling WP_DEBUG in your wp-config.php file. It’s not recommended to have it enabled on a live site.

Hey @mcqtia,

Yes, it looks like an oversight, our development team will make sure to fix it in a newer version. Thanks.

The PHP Warning’s root cause is that a page or post’s original author no longer exists in the database. This is based on the wp_user table’s user ID which is attached to a post and can be seen in the database. After digging through WordPress source code I came up with this solution which should be removed once Yoast patches it. This code can be dropped in anywhere in a theme or plugin but must be hooked before the Yoast plugin.

$original_user = new stdClass();
$original_user->ID = 1;
$original_user->display_name = '';
wp_cache_set(1, $original_user, 'users');

Hi @jeroenrotty

I wondered if there is any update on this fix?
