Here are steps you can take to address this issue:

Check if the Extension is Installed:

Verify that the pdo_sqlsrv extension is installed on your server. You can do this by checking the PHP extensions or running:

bash

php -m | grep pdo_sqlsrv

If it's not installed, you'll need to install it.
Verify File Existence:

Make sure that the file pdo_sqlsrv.so actually exists in the directory specified. Check the path and the presence of the file:

bash
ls -l /path/to/pdo_sqlsrv.so

Replace /path/to/ with the actual path where the file is supposed to be located.
Check php.ini Configuration:

Confirm that the extension is correctly configured in your php.ini file. Open your php.ini file and ensure that there is a line like:

ini

extension=pdo_sqlsrv.so

If it's not there, add it and restart your web server.
Restart Web Server:

After making any changes to your PHP configuration, restart your web server to apply the changes.
Correct any typos:

Double-check for any typos or mistakes in the path or filename. Even a small typo can lead to this error.
Check File Permissions:

Ensure that the pdo_sqlsrv.so file has the correct permissions and is accessible by the user running your web server.
Verify PHP Version Compatibility:

Ensure that the pdo_sqlsrv extension is compatible with the version of PHP you're using. Some extensions may be specific to certain PHP versions.
Reinstall or Update the Extension:

If you're certain the extension is installed but still encountering issues, try reinstalling it or updating it to the latest version.
Consult WHMCS Documentation or Support:

Check the WHMCS documentation or contact their support for specific troubleshooting steps related to this error.
Check SQL Server Connection:

Verify that your SQL Server is running and that the connection details in your WHMCS configuration are correct.

If none of these steps resolve the issue, consider consulting your server administrator or WHMCS support for further assistance. Always exercise caution when making changes to system configurations and ensure that you have backups in place before making any major adjustments.
