How to Enable PHP errors to Display on Web Browser?

Updated: 28 September 2026 · Applies to: cPanel & WHM 138 (Jupiter theme)

Showing PHP errors in the browser helps while developing. Never leave it on for a live site, because errors reveal details of your code.

cPanel

1. Log in to cPanel (for example at https://yourdomain.com:2083, or from the Ucartz client area).
2. Open Software › MultiPHP INI Editor and choose the domain.
3. Set display_errors to Enabled and click Apply.

In your own code (temporarily)

ini_set('display_errors', '1');
error_reporting(E_ALL);

Turn it off again when you are done; the errors are still written to the error_log file.
