You can find the version of PrestaShop from files in several ways:
Method 1: Check config/settings.inc.php (PrestaShop 1.6 and older)
Open:
/config/settings.inc.php
Search for:
define('_PS_VERSION_', '1.6.x.x');
Method 2: Check app/AppKernel.php (PrestaShop 1.7)
Open:
/app/AppKernel.php
Look for something like:
const VERSION = '1.7.x.x';
Method 3: Check src/Core/Version.php (PrestaShop 8)
Open:
/src/Core/Version.php
You may see:
public const VERSION = '8.x.x';
Method 4: Check composer.json
Open:
/composer.json
Search for:
"prestashop/core": "8.x.x"
Method 5: Use PHP file (works on most versions)
Create a file like version.php in root:
<?php
include('config/config.inc.php');
echo _PS_VERSION_;
Open in browser:
https://yourdomain.com/version.php
It will display:
8.1.5
Delete the file after checking for security.
