I received the following error in my Drupal 8 status report:
PRIVATE FILES DIRECTORY Not fully protected See https://www.drupal.org/SA-CORE-2013-003 for information about the recommended .htaccess file which should be added to the private:// directory to help protect against arbitrary code execution.
The obsolete link provided shows no guidance for Drupal 8 or 9, only 7 and prior. I already have what I believe is a strict
.htaccess file I'd found elsewhere in Drupal's documentation. How can I fix this error in Drupal 8?
