Make a backup!
Direct installation of PrestaShop module onto your production web site is not recommended or supported. We advise you to install this on a development version of your web site first to ensure correct operation with your particular PrestaShop installation.
In addition, we advise you to make a complete backup of your PrestaShop system (application files and database) before proceeding.
