Understanding the Error Message

The error message indicates that the MySQL extension, a necessary component for PHP to interact with MySQL databases, is missing or not enabled on your PHP installation. As a result, WordPress is unable to connect to the MySQL database and perform essential operations.

Causes of the Error

Several factors can contribute to this error. It may occur if you have an outdated or misconfigured PHP installation, or if the MySQL extension is not installed or enabled. Additionally, some hosting providers might disable the MySQL extension by default.

Checking PHP Extensions

To resolve this issue, we first need to check if the MySQL extension is enabled in your PHP configuration. Follow these steps:

• Access your hosting account or server.
• Locate the PHP configuration file, typically named php.ini or php.ini.default.
• Open the file using a text editor.
• Search for the line that begins with extension=mysql.
• If the line is commented out with a semicolon (;) at the beginning, remove the semicolon to uncomment it.
• Save the changes and exit the text editor.
