Fatal error: Call to undefined function wp_add_privacy_policy_content() in /wp-admin/includes/misc.php on line 1822

Question

/**
     * Add the suggested privacy policy text to the policy postbox.
     *
     * @since 4.9.6
     */
    public static function add_suggested_content() {
        $content = self::get_default_content( true );
        wp_add_privacy_policy_content( __( 'WordPress' ), $content );
    }

I see the function is added since wordpress version 4.9.6 and my wordpress version is 4.9.8 What can be the issue ?

Answer 1

What I found is the function was defined in wp-admin/includes/plugin.php as mentioned here https://wpseek.com/function/wp_add_privacy_policy_content/ When I opened the plugin.php file of a clean wordpress 4.9.8 version I found the function wp_add_privacy_policy_content() already defined, whereas in my wordpress 4.9.8 version It was missing so I added it back
Kindly make sure the function is defined in plugin.php

/**
 * Helper function for adding content to the Privacy Policy Guide.
 *
 * Plugins and themes should suggest text for inclusion in the site's privacy policy.
 * The suggested text should contain information about any functionality that affects user privacy,
 * and will be shown on the Privacy Policy Guide screen.
 *
 * A plugin or theme can use this function multiple times as long as it will help to better present
 * the suggested policy content. For example modular plugins such as WooCommerse or Jetpack
 * can add or remove suggested content depending on the modules/extensions that are enabled.
 * For more information see the Plugin Handbook:
 * https://developer.wordpress.org/plugins/privacy/suggesting-text-for-the-site-privacy-policy/.

 * Intended for use with the `'admin_init'` action.

 * @param string $plugin_name The name of the plugin or theme that is suggesting content for the site's privacy policy.
 * @param string $policy_text The suggested content for inclusion in the policy.
