Your PHP installation appears to be missing the MySQL extension

If you’re seeing this error message, it means that the MySQL extension for PHP is not installed or enabled on your system. This extension is required to connect to and interact with MySQL databases using PHP.

To resolve this issue, you will need to install the MySQL extension for PHP. Here are some steps you can follow:

1. Check if the MySQL extension is installed: You can check whether the MySQL extension is already installed on your system by creating a PHP file with the following code:
   <?php
   phpinfo(); ?>
2. Install the MySQL extension: Depending on your operating system and PHP version, the steps to install the MySQL extension may differ. Here are some commands to install the extension on popular Linux distributions:
3. Enable the MySQL extension: Once the extension is installed, you need to enable it in your PHP configuration. You can do this by editing the php.ini file and uncommenting the line that starts with “extension=mysql.so” or “extension=mysqli.so”, depending on the version of PHP you’re using.
4. After making changes to the php.ini file, don’t forget to restart your web server to apply the changes.
5. If you’re still having issues, you may need to contact your web hosting provider or system administrator for assistance.
   

I did not change a thing but went to my site and got the

“Your PHP installation appears to be missing the MySQL extension which is required by WordPress. Please check that the mysqli PHP extension is installed and enabled” message and no page load.

Latest DIVI theme, PHP is 8.1, WP is 6.2.2, a few plugins are up to date (LiteSpeed Cache and Classic Widgets) I did not change anything so what could be the problem?

I had this problem after I updated my php setting to php8.3, and then I changed the setting to php8.0 and things worked fine.

Hope this helps.
