So, you're running PHP7.2 but [https://liorkaplan.wordpress.com/2017/09/10/php-7-2-is-coming-mcrypt-extension-isnt/ can't install php7.2-mcrypt like you used to]?
<source lang="bash">
# install dependencies
sudo apt-get -y install libmcrypt-dev
# use PECL to install mcrypt
sudo pecl install mcrypt-1.0.1
</source>

sudo phpenmod mcrypt
# confirm with
php -m | grep mcrypt
</source>
Now, tell Apache to use your new PHP module:
<source lang="bash">
sudo systemctl reload apache2
# confirm with
