Rochen support staff can install a PEAR module for you, if it is not already installed on your server.
Simply open a support ticket with us via My Rochen at: https://my.rochen.com requesting that we install the module.
Please be sure to include the full module name as well as the name of the server hosting your website in the support ticket to ensure swift installation.
PEAR stands for PHP Extension and Application Repository. A useful resource for general information on PEAR modules is the PEAR subsite of the official PHP website at: http://pear.php.net.
