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. Under the Account Global Settings, go to the Options tab.
Note: If it shows an error related to the Native PHP version, change to a non-Native PHP 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.
