 * When updated to php7 on my wordpress server, I recently see this kind of errors:
 * [error] 16377#0: *46 FastCGI sent in stderr: “PHP message: PHP Warning: call_user_func_array()
   expects parameter 1 to be a valid callback, function ‘hammy_options_init’ not
   found or invalid function name in {$wordpressdir}/wp-includes/plugin.php on line
   525” while reading response header from upstream, client: 91.126.128.242, server:
