No, they are both set to false. I just discovered that the login page on the front end is blank even for regular customers though, it's not actually the place order button that is the issue. The problem is with the code in the login/header_php.php file, but I have been unable to determine the cause. No log files are being generated. The site is on version 1.5.1.

Are you sure that your admin's /includes/configure.php file doesn't indicate that your store-front uses SSL? If you're not using SSL, then your admin's configure.php file should look similar to:
Code:
/**
 * WE RECOMMEND THAT YOU USE SSL PROTECTION FOR YOUR ENTIRE ADMIN:
 * To do that, make sure you use a "https:" URL for BOTH the HTTP_SERVER and HTTPS_SERVER entries:
 */
  define('HTTP_SERVER', 'http://www.example.com');
  define('HTTPS_SERVER', 'https://www.example.com');
  define('HTTP_CATALOG_SERVER', 'http://www.example.com');
  define('HTTPS_CATALOG_SERVER', 'https://www.example.com');

  // secure webserver for admin?  Valid choices are 'true' or 'false' (including quotes).
  define('ENABLE_SSL_ADMIN', 'false');

  // secure webserver for storefront?  Valid choices are 'true' or 'false' (including quotes).
  define('ENABLE_SSL_CATALOG', 'false');
