Sometimes, you eill need to debug PHP, and for that, you will need to enable display_errors or disable them for security reasons.
This is how you can do that by using the CloudLinux Selector to enable or disable PHP's display_errors in cPanel.
1. Log in to your cPanel Account.
2. In the Software section, click on Select PHP Version.
3. Click on the Options menu.
Keed in mind: 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, check its box.
For disabling it, uncheck it.
