BUG REPORT

Congratulations for this plugin ! Just a note though: pf-404.php does not work on a PHP7 server: mysql_real_escape_string() was deprecated in PHP 5.5.0, and it was removed in PHP 7.0.0. (Two lines should be modify, 621 and 668 with mysqli_real_escape_string: http://php.net/manual/en/function.mysql-real-escape-string.php). Thank you very much for this amazing code !
