Your PHP installation appears to be missing the MySQL extension which is required by WordPress

It means the PHP installation on your server doesn’t have the required MySQL extension to connect WordPress to your MySQL database. Support for this extension was deprecated in versions of PHP 7.0 and beyond.

This means that if you’re seeing this message, your WordPress site’s code isn’t compatible with the version of PHP you’re using. More specifically, it can indicate that:

  • Your WordPress files are outdated
  • The MySQL extension isn’t installed or enabled
  • The PHP extension is not configured properly

This issue is most common with new WordPress installations, especially for certain operating systems that don’t include the MySQL extension by default, such as Linux. It may also occur when migrating a site or changing your server configuration.

  1. Make Sure the MySQL Extension Is Installed
    If updating WordPress doesn’t help, the next step is to verify whether the MySQL extension is installed and enabled. Some operating systems don’t include the MySQL extension by default. If you’re using one of them, you’ll need to install it yourself.

First, create an info.php file in the root directory (public.html) of your WordPress site via FTP. It should contain the following:

Save your file, then visit it in your browser (https://www.yourdomain.com/info.php). You’ll see a page with the details of your PHP installation.

Look for the mysql or mysqli section. If the extension is installed, it will display the version next to Client API:

    At this point, if the issue still isn’t fixed, it’s likely that your PHP extension directory is not configured properly (or at all). Navigate back to the PHP info page in your browser to check by looking for “Loaded Configuration File“.

However, if yours is pointing to the incorrect location, you’ll need to edit your php.ini file to replace it with the correct one.
