Common Causes of the Error
PHP Version Incompatibility
One common cause of the “wordpress error missing MySQL extension” is PHP version incompatibility. WordPress relies on the MySQL extension to establish a connection with the database. However, certain PHP versions might not have the necessary MySQL extension installed or enabled by default, leading to this error.
Missing MySQL Extension
Another common cause is the absence of the MySQL extension on the server. This extension is required for WordPress to communicate with the database. If the server does not have the MySQL extension installed or enabled, it can result in the “wordpress error missing MySQL extension.”
Checking PHP Version Compatibility
Verifying PHP Version
To address the issue of PHP version incompatibility, the first step is to check the currently installed PHP version on your server. You can do this by creating a simple PHP script and running it on your server. The script will display the PHP version information.
Upgrading PHP Version
If you discover that your PHP version is outdated or incompatible, you may need to upgrade to a newer version. Check the official PHP website for the latest stable release and follow their documentation or consult your web hosting provider on how to upgrade your PHP version.
Downgrading PHP Version
Sometimes, upgrading to the latest PHP version might cause compatibility issues with specific plugins or themes. In such cases, you may need to consider downgrading your PHP version to a previous stable release. Consult your web hosting provider or the official PHP website for guidelines on how to downgrade PHP.

Installing or Enabling MySQL Extension
Check for Existing MySQL Extension
Before proceeding with the installation or enabling of the MySQL extension, it’s crucial to verify if it is already present on your server. You can do this by accessing the PHP Info page, which displays detailed information about your PHP configuration. Look for the MySQL extension in the list of loaded extensions.
Installing MySQL Extension
If the MySQL extension is not installed on your server, you will need to install it. The process may vary depending on your hosting environment. You can either contact your web hosting support for assistance or refer to the official PHP documentation for guidance on installing the MySQL extension.
Enabling MySQL Extension
In some cases, the MySQL extension might be installed but not enabled in the PHP configuration. To enable it, locate the php.ini file on your server and open it using a text editor. Look for the line containing “extension=mysql.so” (or “extension=php_mysql.dll” on Windows systems) and remove any preceding semicolon (;) to uncomment the line. Save the changes and restart the web server.
Verifying MySQL Extension
After installation or enabling, it is essential to verify that the MySQL extension is now active. You can do this again by accessing the PHP Info page and checking if the MySQL extension is listed among the loaded extensions.
Modifying php.ini Configuration
Locating php.ini File
The php.ini file contains important configuration settings for PHP. To modify it, you need to locate the correct php.ini file on your server. The location can vary depending on your hosting environment. One way to find it is by creating a PHP file with the following code:
Save the file as info.php and upload it to your server. Access the file through your web browser and search for the “Loaded Configuration File” value. This will indicate the path to your php.ini file.
Once you have located the php.ini file, open it using a text editor. Look for the section related to extensions and find the line that starts with “extension=mysql.so”. If you are on a Windows system, it may begin with “extension=php_mysql.dll”. Remove any preceding semicolon (;) to uncomment the line. Save the changes.
Restarting Web Server
After modifying the php.ini file, it is necessary to restart the web server for the changes to take effect. This can usually be done through your hosting control panel or by contacting your web hosting support for assistance. Restarting the web server ensures that the new configuration is applied.

Troubleshooting Database Connection
Checking Database Credentials
A misconfiguration of the database credentials can also lead to the “wordpress error missing MySQL extension.” Double-check the database details in your WordPress configuration file (wp-config.php). Ensure that the database name, username, password, and host information are correct. Any discrepancies can prevent WordPress from establishing a connection with the database server.
Testing Database Connection
To troubleshoot the database connection, you can try connecting to the database server manually using a tool like phpMyAdmin or a database management software. Verify that you can connect successfully using the same credentials mentioned in the wp-config.php file. If the connection fails, it indicates an issue with the database server or the provided credentials.
If the database connection is established successfully, but you still encounter the “wordpress error missing MySQL extension,” there might be a problem with the WordPress database itself. In this case, you can try repairing the database by accessing the WordPress administration dashboard, navigating to “Tools,” and selecting “Database Repair.” Follow the on-screen instructions to repair the database tables.
If all else fails, you may need to consider reinstalling WordPress to address the “wordpress error missing MySQL extension.” Before proceeding with the reinstallation, make sure to create a backup of your existing WordPress files and database. Follow the official WordPress documentation or contact your web hosting support for guidance on the reinstallation process.
Updating WordPress and Plugins
WordPress regularly releases updates that not only introduce new features but also fix bugs and security vulnerabilities. It is crucial to keep your WordPress installation up to date. To update WordPress, log in to the WordPress administration dashboard and navigate to the “Updates” section. Click on the “Check Again” button to search for available updates, and then click on “Update Now” to install the latest version.
Outdated or incompatible plugins can sometimes cause conflicts and lead to errors like the “wordpress error missing MySQL extension.” It is essential to keep your plugins up to date. To update plugins, go to the “Plugins” section in the WordPress administration dashboard, and look for any plugins that have available updates. Click on the “Update Now” link below each plugin to install the latest version.
After updating WordPress and plugins, it’s essential to check for compatibility issues. Some plugins may not yet be compatible with the latest WordPress version or with each other. Monitor your website closely for any errors or malfunctions after updating, and if you encounter any issues, try deactivating or updating the problematic plugins. You can also seek assistance from the plugin developers or support forums for further guidance.
