In cases where PHP scripts were working fine previously but suddenly encounter errors, what steps can be taken to identify and rectify the problem, especially if it involves server configuration changes?

If PHP scripts were working fine previously but suddenly encounter errors, it may be due to server configuration changes. To identify and rectify the problem, you can check the server error logs for any clues, verify the PHP configuration settings, and ensure that any recent changes to the server configuration are compatible with the PHP scripts being used.

// Check server error logs for clues
error_log("Checking server error logs for any clues");

// Verify PHP configuration settings
phpinfo();

// Ensure recent server configuration changes are compatible
// with PHP scripts being used
