Other recommendations
Safe Mode
PHP's Safe Mode is deprecated in the latest version of PHP, and
should not be used anymore. For PrestaShop in particular, having Safe
Mode on can render your payment modules useless.
Updates
Your applications' PHP code is the only vulnerable path to your server. It is
therefore strongly recommended to always update your server's
applications: PHP, MySQL, Apache and any other application on which
your website runs.
Miscellaneous
The PrestaShop file structure
The PrestaShop developers have done their best to clearly and intuitively
separate the various parts of the software.
