 * Is there anyone who can address this PHP warning?
 * PHP Warning: The magic method jtmce\core\Singleton::__wakeup() must have public
   visibility in /home/customer/www/DOMAIN/public_html/wp-content/plugins/just-tinymce-
   styles/core/Singleton.php on line 60
   Or are there any alternatives where we can
   add custom styles to a TinyMCE drop down in Classic Editor?
