[error] 6717#6717: *4360 FastCGI sent in stderr: “PHP message: PHP Fatal error: Class ‘WPSEO_Dismissible_Notification’ not found in /var/www/x.com/wp-content/plugins/wordpress-seo/admin/notifiers/class-post-type-archive-notification-handler.php on line 11” while reading response header
My error.log is full of these after I’ve updated today and I cannot access the /wp-admin, receiving 500 error.
Please, help.
