Step 2: System Requirements Check

The installer will automatically check if your server environment meets all the necessary requirements. If any checks fail, you'll need to contact your hosting provider to enable the missing extensions.
Minimum Server Requirements:
  • ✅ PHP version 7.2 or higher
  • ✅ MySQL Database (Version 5.7+)
  • ✅ MySQLi extension for PHP
  • ✅ GD extension for PHP (for image processing)
  • ✅ ImageMagick (Optional, for better image quality)

Step 3: Connect to Your Database

Enter the connection details for your MySQL database. You'll need to create an empty database in your hosting control panel (cPanel, Plesk, etc.) first. Then, provide the database name, username, and password here.

You can also import a location database for your country here to save time later.
