wordpress error in local server

I download Sunny Blue Sky theme-1.0.9 from www.remarpro.com
when i want to access the page from local server the browser show a message that “The site’s security certificate is not trusted” and also provide 2 options first is Processed anyway, second is Back to safety.
Then i observe the browser title bar SSl Error.
When i click Processed any way then my page is viewed.
After then I add Secure WordPress plugins,then an message is shown top of the header image that is”Warning: file_exists() [function.file-exists]: Unable to find the wrapper “https” – did you forget to enable it when you configured PHP? in C:\xampp\htdocs\wordpress\wp-content\plugins\secure-wordpress\secure-wordpress.php on line 570″
that code is

/**
         * add index.php to plugin-derectory
         */
        {
 567     public function add_index($path, $enable)
            $file = trailingslashit($path) . 'index.php';
            if ($enable) {
 570             if (!file_exists($file)) {
 571                 $fh = @fopen($file, 'w');
                    if ($fh) {fclose($fh);}
                }
            }
            else {
                if (file_exists($file) && filesize($file) === 0) {
                    @unlink($file);
                }
            }
580      }

After that i block that code such as
        /**
         * add index.php to plugin-derectory
         */
        {
        public function add_index($path, $enable)
            $file = trailingslashit($path) . 'index.php';
            if ($enable) {
                //if (!file_exists($file)) {
                  //  $fh = @fopen($file, 'w');
                //    if ($fh) {fclose($fh);}
                //}
            }
            else {
                if (file_exists($file) && filesize($file) === 0) {
                    @unlink($file);
                }
            }
        }
