 * Hi,
 * Great firewall. We are getting the following warning and wonder if there is something
   that should be done about it:
 * “Use of undefined constant MYSQLI_CLIENT_SSL_DONT_VERIFY_SERVER_CERT – assumed‘
   MYSQLI_CLIENT_SSL_DONT_VERIFY_SERVER_CERT’ (this will throw an Error in a future
   version of PHP)”
 * Location: plugins/ninjafirewall/lib/firewall.php:374

 * I don’t know why your PHP version doesn’t define the MYSQLI_CLIENT_SSL_DONT_VERIFY_SERVER_CERT
   constant but another user had the same issue:

 * The next version will check and fix it.
