With anonymous submissions enabled your site will require a Cloudflare Turnstile Site Key / Secret Key to accept submissions. With out these your visitors will be shown the following error when submitting a document.

When using the enhanced upload form on an intranet site that cannot be accessed from the internet you can tell DLP Power Pack to skip the security checks by adding the following setting in your sites wp-config.php.

define('DLPP_BYPASS_TURNSTILE', true);

You can check this setting is being used by also setting WP_DEBUG to true.

define('WP_DEBUG', true);

With debug set to true you will see this debug mode notice shown on the page, letting you know that Turnstile verification is bypassed. Return your WP_DEBUG to false to hide this message again.
