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 cPanel.
1. Log in to your cPanel account.
2. In the Software section, click on Select PHP Version.
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.
The message will show that the option is enabled or disabled.
