Understanding the Error Message

Why Does this Error Occur?

How to Fix the Error
Now that we understand the error message and its possible causes, let’s move on to the solutions. Here are a few methods you can try:
1. Check PHP Version and Configuration
Make sure you are using a PHP version that supports the MySQL extension. You can check your PHP version by creating a PHP info file and accessing it through your web browser. Look for the “mysql” section in the PHP info file to confirm if the extension is enabled.
2. Install or Enable the MySQL Extension
If the MySQL extension is missing or disabled, you will need to install or enable it. The process may vary depending on your server environment. Here are a few common methods:
a) Installing the MySQL Extension
If you have access to your server’s terminal or command line, you can try installing the MySQL extension using the package manager. For example, on Ubuntu, you can use the following command:
sudo apt-get install php-mysql
b) Enabling the MySQL Extension
If the MySQL extension is already installed but disabled, you will need to enable it in your PHP configuration file. Locate your php.ini file and uncomment or add the following line:
extension=mysql.so
3. Consider Alternative Database Extensions
If you are unable to install or enable the MySQL extension, you can consider using alternative database extensions supported by WordPress, such as MySQLi or PDO (PHP Data Objects). These extensions offer similar functionality and can be used as drop-in replacements for the MySQL extension.
4. Consult with Your Hosting Provider
If you are not comfortable making changes to your server configuration or are unsure about the steps to take, it is recommended to reach out to your hosting provider’s support team. They will be able to assist you in resolving the issue or provide further guidance specific to your server environment.
