    Apparently, your WordPress version is too old. This function was introduced in WordPress 4.9.
    You can edit this file: wp-content/plugins/ninjafirewall/lib/utils.php
    Line 20, there’s this code:

    if (! defined( 'NFW_ENGINE_VERSION' ) ) { die( 'Forbidden' ); }

    Below, line 21, add this code:

    // For WP <4.9.
if (! function_exists( 'readonly' ) ) {
   function readonly( $var, $val) {
      if ( $var == $val ) {
         echo " readonly='readonly'";
      }
   }
}
