In this Prestashop tutorial, we will guide through the steps to update your database connection.


Get the new database connection settings ready

Upload an up to date database backup file within the target database instance.

Setting up a new Database in Prestashop 1.7

You could update your Prestashop files via an FTP connection or directly from your domain cPanel application. We recommend the first method.

Use your FTP credentials to connect to your website.  Once connected, navigate to the file:


Download the file in your local computer. Edit the file parameters.php with a simple text editor like Notepad++.

Look for the parameters:

  • Database_host
  • Database_name
  • Database_user and
  • database_password

Replace every single of the parameters with the new ones that Save the file to apply the updates and upload the file to replace the old parameters.php document.
