My checkout suddenly goes to a white page, it never used to do this!

The error I am getting is

Call to undefined function mcrypt_module_open() in /var/www/vhosts/mywebsite.co.uk/httpdocs/lib/Varien/Crypt/Mcrypt.php on line 63

PLEASE HELP! Thank you very much

This could be caused by a recent upgrade to PHP and you are missing PHP Mcrypt module.

To install it's usually a simple apt-get install php5-mcrypt on Ubuntu/Debian. A Google search should turn up the correct instructions for your PHP and OS version.

    TIL you may need to run php5enmod mcrypt on some systems after installing mcrypt via the system's package manager.

  • If apt-get install php5-mcrypt doesn't work, you can try apt-get install php53-mcrypt.

In most of the cases, this issue comes in php updated version i.e. php7 and if mcrypt is not installed -

to install it, follow the below steps:

sudo apt-get update
sudo apt-get install mcrypt php7.0-mcrypt
sudo apt-get upgrade
sudo service apache2 restart
