PHP не выполняется proxy_fcgi и php_fpm в веб-интерфейсе Zabbix

Я установил php7.0-fpm и включил мод proxy_fcgi для веб-интерфейса Zabbix.

Однако, когда я пытаюсь получить доступ с любой страницы, я получаю исходный код PHP этой страницы вместо обычной страницы.

Мои конфиги следующие:

/etc/php/7.0/fpm/pool.d/www.conf
[www]
user= www-data
group = www-data
listen = /run/php/php7.0-fpm.sock
listen.owner = www-data
listen.group = www-data
listen.mode = 0660
pm = dynamic
pm.max_children=10
pm.start_servers =5
pm.min_spare_servers = 2
pm.max_spare_servers = 7
chdir = /usr/share/zabbix/

/etc/apache2/sites-enabled/zabbix.conf 
<VirtualHost *:80>
    Include conf-available/zabbix.conf
    <FilesMatch \.php$>
    SetHandler "proxy:unix:/run/php/php7.0-fpm.sock|fcgi://localhost/usr/share/zabbix/"
    </FilesMatch>
</VirtualHost>

Я получаю только исходный код php при любом доступе к странице:

require_once dirname(__FILE__).'/include/config.inc.php';

В логах все четко, ошибок нет вообще.

Не могли бы вы помочь?
