344: How to reset your admin password in PrestaShop 1.5

If you have a database configuration error, it can display in different ways. If error reporting is not turned on, it will show differently according to the browser.

Googe Chrome

The website encountered an error while retrieving http://domain.com/ It may be down for maintenance or configured

FireFox Generally displays a blank page
Internet Explorer

The website cannot display the page

While these messages are fairly general and can be for different errors as well, it is best to then turn on the error reporting as shown in a previous article. The error should then display with the beginning portion reading "Fatal error: Uncaught exception 'PrestaShopDatabaseException' with message 'Link to database cannot be established."

To troubleshoot the database configuration:

  1. Log into your hosting control panel, SSH, or FTP client.
  2. Navigate to the PrestaShop 1.5 root folder.
  3. From there, find your way to the config folder.
  4. Once in the config folder, locate the file named settings.inc.php This is the file with all of the database settings.
  5. The table below shows your the four database settings. Ensure that each one is correct. The data shown is sample data, so you will need to know the connection data for your own installation.

    define('_DB_SERVER_', 'localhost');

    define('_DB_NAME_', 'your_database_name');

    define('_DB_USER_', 'your_database_user_name');

    define('_DB_PASSWD_', 'your_database_password');

  6. Once you have corrected the database settings and saved the file, refresh the page to see if the site displays. If so, you may turn off the error reporting.

That is how you troubleshoot a database connection error in PrestaShop 1.5.

Hello Vivian,

Thank you for your question. You will need to create the database, then create the database user, and password and attach them to the database.

If you have any further questions, feel free to post them below.

Thank you,

Unfortunately the password would not be displayed anywhere but you could create a new user with a new password, attach it to the database, then edit the wp-config.php with the new user and password.

Best Regards,
TJ Edens
