Sometimes, we need to debug PHP. Hence, we need to enable display_errors or disable them for security reasons. You can do this using the CloudLinux Selector to enable or disable PHP's display_errors in Plesk.
1. Log in to your Plesk account.
2. In the right-hand sidebar, click on PHP Selector.
3. Click on the Options menu.
Note: If the Options page shows an error related to the native PHP version, change it to a non-native version first.
4. For enabling display_errors, tick mark it. For disabling it, uncheck it.
