Take a look at this https://stackoverflow.com/questions/29993399/use-of-undefined-constant-mcrypt-rijndael-128-assumed-mcrypt-rijndael-128

Run this in console

php -m | grep mcrypt

It should return

mcrypt

If not, be sure to enable module using phpenmod command

Another reference, for php5 http://php.net/manual/es/mcrypt.installation.php

Note, for Ubuntu, simply installing php5-mcrypt did not get mcrypt to work. You need to execute the following commands as root to enable it:

apt-get install php5-mcrypt

mv -i /etc/php5/conf.d/mcrypt.ini /etc/php5/mods-available/

php5enmod mcrypt

service apache2 restart
