phpmyadmin ошибка обработки запроса 200

Несколько дней назад я изменил файл phpmyadmin config.inc.php моего Wamp для автоматической аутентификации. Phpmyadmin работал нормально, но теперь, когда я щелкаю где-нибудь в phpmyadmin, он выдает мне эту ошибку в всплывающем окне:

Ошибка в обработке запроса

Код ошибки: 200

Текст ошибки: ОК

Это мой файл config.inc.php:
