WordPress is built using PHP programming language and it requires a database to store all the information such as posts, pages, users, comments, etc. MySQL is one of the most popular databases used with WordPress.
The PHP extension responsible for interacting with MySQL is called “mysql” or “mysqli” depending on the version of PHP. So, if this extension is not installed or enabled, WordPress will not be able to connect to the MySQL database and you will see this error message.
If you are using a PHP version that is 5.0 or lower than 5.0 then the chances are you are going to see this error.
To fix this issue, you will need to install or enable the “mysql” or “mysqli” PHP extension on your server.
You have the extension but it still gives this error?
If you have confirmed that the “mysql” or “mysqli” PHP extension is installed and enabled on your server, but you are still seeing the error message “Your PHP installation appears to be missing the MySQL extension which is required by WordPress”, then there could be a few other reasons why this error is occurring.
Here are a few things you can try to resolve this issue:
1- Check the php.ini file
Make sure that the “mysql” or “mysqli” extension is listed in your php.ini file and that it is not commented out. You can find your php.ini file location by creating a new PHP file and using the phpinfo() function to display the PHP configuration settings.
Below is the code that you need to put into the file and place the file in the root directory of your website.
<?php phpinfo(); ?>
2- Restart web server
After modifying the php.ini file, restart your web server to ensure that the changes take effect.
3- Check the version of PHP:
Make sure that you are using a compatible version of PHP with WordPress. Check the WordPress documentation for the recommended version of PHP and make sure your server is running that version.
4- Check file permissions
Make sure that the PHP files and directories that WordPress needs to access have the correct permissions. Typically, files should have a permission of 644 and directories should have a permission of 755.
5- Disable plugins and themes
Sometimes, a plugin or theme may conflict with the “mysql” or “mysqli” extension, causing this error. You can try disabling all plugins and switching to a default theme to see if that resolves the issue.
If none of these solutions work, you may want to consider contacting your web hosting provider or a WordPress developer for further assistance.
