How to fix server version on PrestaShop

Steps for PrestaShop

1. PrestaShop is self-hosted, so the fix is applied at the server level.
2. On Apache: open .htaccess in your PrestaShop root (or the server's httpd.conf/vhost config) and add `Header unset Server` and `Header unset X-Powered-By`. Ask your host to set `ServerTokens Prod` in the main config.
3. On Nginx: add `server_tokens off;` in nginx.conf or the site server block; use headers_more to fully clear the header.
4. In PrestaShop's back office, there is no built-in setting for this — it must be done at the server/host level.
5. Set `expose_php = Off` in php.ini if your host allows it.
6. Use a hosting control panel (cPanel, Plesk) if available to modify PHP settings and .htaccess.

# Apache (httpd.conf or .htaccess)
ServerTokens Prod
ServerSignature Off
Header unset X-Powered-By

# Nginx (nginx.conf — inside http{} or server{} block)
server_tokens off;
# (requires headers_more module for full removal:)
more_clear_headers 'Server';
more_clear_headers 'X-Powered-By';

# PHP (php.ini)
expose_php = Off

# Next.js (next.config.js)
module.exports = { poweredByHeader: false }

What is server version?

Every time a visitor's browser (or a bot) loads a page on your store, your web server sends back a set of invisible "response headers." One of these is the `Server` header, and by default most web servers announce themselves with their exact name and version number — for example, `Server: Microsoft-IIS/10.0` or `Server: Apache/2.4.51`. A related header, `X-Powered-By`, can also reveal the scripting language or framework version (e.g., `X-Powered-By: PHP/8.1.2`). Together these are called "server version disclosure" or "banner grabbing." Neither header has any meaningful purpose for shoppers — they exist purely as leftover defaults.

Advertising your exact server software and version is like posting a sign on your shop door listing every lock brand and model you use. Automated attack tools (bots) continuously scan the internet for sites running specific software versions with known vulnerabilities. When your version is visible, your store becomes an easy target: attackers can instantly match your version against published vulnerability databases (CVE lists) and launch targeted exploits — without any guesswork. Suppressing these headers does not make your server invulnerable, but it removes you from the easiest tier of automated attack campaigns. It also demonstrates security hygiene to enterprise buyers and payment-card auditors (PCI DSS Requirement 2.2.7 addresses unnecessary information disclosure), reducing compliance friction.
